Abstract ：
Subway systems are a crucial component of urban public transportation, especially in terms of safety during seismic events. Soil liquefaction triggered by earthquakes is one of the key factors that can lead to underground structural damage. This study investigates the impact of deep soil liquefaction on the response of subway station structures during seismic activity, aiming to provide evidence and suggestions for earthquake-resistant measures in underground constructions. The advanced finite element software PLAXIS was utilized for dynamic numerical simulations. Non-linear dynamic analysis methods were employed to construct models of subway stations and the surrounding soil layers, including soil-structure interactions. The UBC3D-PLM liquefaction constitutive model was applied to describe the liquefaction behavior of soil layers, while the HS constitutive model was used to depict the dynamic characteristics of non-liquefied soil layers. The study examined the influence of deep soil liquefaction on the dynamic response of subway station structures under different seismic waves. The findings indicate that deep soil liquefaction significantly increases the vertical displacement and acceleration responses of subway stations compared to non-liquefied conditions. The liquefaction behavior of deep soil layers leads to increased horizontal effective stress on both sides of the structure, thereby increasing the horizontal deformation of the structure and posing a potential threat to the safety and functionality of subway stations. This research employed detailed numerical simulation methods, incorporating the non-linear characteristics of deep soil layer liquefaction, providing an analytical framework based on regulatory standards for evaluating the impact of deep soil liquefaction on the seismic responses of subway stations. Compared to traditional studies, this paper significantly enhances simulation precision and practical applicability. Results from this research indicate that deep soil layer liquefaction poses a non-negligible risk to the structural safety of subway stations during earthquakes. Therefore, the issue of deep soil liquefaction should receive increased attention in engineering design and construction, with effective prevention and mitigation measures being implemented.

Abstract ：
Fault dislocation causes deformation of the surrounding rock mass, which is the main factor leading to the destruction of buried pipeline structures. In this paper, we introduce the Pasternak double-parameter model to accurately consider the nonlinear interaction between the pipeline and the foundation. The pipeline's longitudinal response to fault dislocation is determined using the complementary error function. The analytical solution is validated through numerical simulations and existing literature, demonstrating its applicability and feasibility. Additionally, a comprehensive sensitivity analysis is conducted on the fault dip and coefficient of subgrade reaction. The analytical solution confirms the numerical simulation and previous research, demonstrating its effectiveness in analysing pipeline response to fault dislocation. The displacement, bending moment, and shear force of the pipeline structure vary with fault dip angles. Increasing the coefficient of subgrade reaction reduces the affected area of the pipeline structure, indicating stronger foundation restraint. The pipeline structure in the affected area undergoes significant changes, leading to stress concentration and making it the primary zone for disasters. Our study results demonstrate an improved understanding of longitudinal response and effective methods to enhance pipeline anti-dislocation capability during fault dislocation.

Abstract ：
In order to study the seismic response of deep non-circular tunnels under far-field seismic SV waves, a pseudo static analytical solution for the seismic response of the tunnel was first derived by using complex variable function theory and conformal mapping method. The proposed analytical solution can take into account variations in the lining thickness and the different interactions between the surrounding rock and lining. Then, the validity and correctness of the analytical solution were verified by numerical methods based on engineering examples of circular, elliptical and horseshoe tunnels. Finally, the significant effects of key parameters, such as the surrounding rock-lining interface conditions, the lining cross-sectional geometry, and the relative stiffness of the surrounding rock and the lining, on the seismic response of the tunnel were discussed. The results showed that with the increase in the interface flexibility coefficient, the normalized thrust of elliptical and horseshoe linings decreased, the deformation increased, and the moment first increased and then decreased. The influence of cross-sectional shape on the internal force of the lining is complex. The large-span and flat lining of the tunnel had large deformation and surrounding rock stress. The increase in the elastic modulus of the surrounding rock or the decrease in the lining thickness resulted in a decrease in the lining thrust and moment and an increase in the deformation. The reasonable combination of rock stiffness and lining thickness can be used to achieve the optimal balance between the internal forces and deformation of the flexible lining in the seismic design of the tunnel. The proposed solution can be easily and quickly applied to the preliminary analysis and prediction of the seismic internal force and deformation of deep tunnels, providing a theoretical basis and scientific reference for engineering seismic design and evaluation.

Abstract ：
In order to study the seismic response characteristics of the giant-span flat cavern (GSFC), a nonlinear finite element model of the GSFC was firstly established by ABAQUS software to investigate the seismic deformation characteristics and stress variation law of the GSFC in detail. Secondly, the bearing mechanism of the GSFC was systematically analyzed. Finally, the damage evolution law and failure mechanism of the GSFC were revealed. The results showed that the deformation, stress and damage of the GSFC under design and rare earthquakes were within safe and controllable limits. The interaction between the linings had a certain damping and peak -elimination effect. When the PGA was 0.2 g, the peak acceleration of the inside lining was reduced by 10% compared to the outside lining, the deformation response was reduced by 39%, and its seismic stress distribution was more uniform. In the bearing system of the GSFC, the surrounding rock was supported the lining so that its self-bearing capacity was fully utilized, while the lining was embedded by the surrounding rock, improving its integrity and stiffness. Under extreme earthquakes, the damage evolution processes of the surrounding rock and the lining were coupled with each other. The continuous plastic strain occurred mainly at the bottom and top of the surrounding rock. The outside lining was mostly destroyed, and the inside lining gradually degraded into a double-hinged arch structure supported by the side walls, so that the seismic performance of the surrounding rock-lining bearing system was lost. The degraded structure can maintain a relatively stable vertical self -equilibrium state and is not prone to extreme damage such as overall collapse. The research conclusions could provide a theoretical basis and scientific reference for accurate seismic prediction and safety evaluation of the GSFC.

Abstract ：
In order to study the dynamic characteristics of the prefabricated subway station structure (PSSS), a finite element model was developed to simulate interaction among the soil, the envelope structure, and the underground PSSS during earthquakes. Numerical simulation and analysis of the nonlinear seismic responses of the PSSS were implemented. The dynamic relative horizontal deformation of structure and the stress responses on the components were analyzed in detail. The seismic damage characteristics of the PSSS were discovered preliminarily. The results indicated that within the seismic fortification levels, the PSSS had excellent seismic performance and met the seismic performance requirements of the current standard. The additional influence of vertical ground motion on the seismic response of PSSS could not be ignored. Due to the significant increase in damage under the giant earthquakes, the side walls, the crown arch, and the envelope structure were the weak positions for earthquake resistance, which should be given sufficient attention. The research conclusions could provide reasonable reference and guidance for the seismic design of the PSSS.

Abstract ：
锚索-抗滑桩组合结构是高大边坡加固的主要措施.加固设计时,传统的安全系数不能考虑地震波频谱特性的影响.为了准确的评价边坡的稳定性,开展性能设计方法的研究.基于极限分析法,推导了抗滑桩位移公式.在易损性的框架下对比了远、近场地震波的差异.结果表明:(1)将结构非线性模型引入到Newmark法可以实现抗滑力的实时更新.指数模型的评估结果更保守.(2)考虑到地震荷载存在较大的离散性,基于性能的设计方法更具合理性.易损性曲线可以用来定量分析边坡的失稳概率.(3)边坡的破坏状态与地震强度和地震动类型有关.当地震强度较低时,失效模式以轻微损坏和中等损坏为主.随地震强度增大,边坡更易发生严重破坏.近场脉冲地震具有能量大、冲击强的特点,更容易造成边坡的失稳.

Abstract ：
The pre-support of large-diameter pipe curtains plays an active role in controlling the deformation of excavations, and the layout of the pipe curtains can be divided into vertical and horizontal types. Based on the measured data of Pinganli metro station in Beijing, the horizontal pipe curtains with lock are simplified into the elastic thin plates, and the results of the elastic plate theory and the continuous beam theory are compared and analyzed. Finally, the influences of excavation span, height of overburden, wall thickness of steel pipes and elastic modulus of grouting materials are analyzed. The results show: (1) The results of the settlement calculation of the elastic thin plate theory are in good agreement with the measured data both in the settlement trend and in the final settlement, while the calculated results of the simply supported beams and the elastic foundation beams are only in good agreement with the measured ones in the final settlement. (2) Under the same load conditions, the maximum bending moment calculated by the elastic thin plate theory is slightly larger than that of the simply supported beams, but this difference is not more than 10%. (3) The elastic modulus of slurry and the thickness of the steel pipe wall have small effects on the settlement and bending moment of the pipe curtains, while the excavation span and the height of overburden have great influences on the settlement and bending moment of the pipe curtains. The research results may provide a new way to simplify pipe curtains into homogeneous elastic thin plates for calculation, and provide the theoretical support for design of the pipe curtains. © 2021, Editorial Office of Chinese Journal of Geotechnical Engineering.

Abstract ：
There are several well-established jacking force empirical models available for predicting the jacking force. However, the jacking force calculated by different empirical formulas have big difference and the face resistance is difficult to measure directly. These factors constrain the prediction of the jacking force in design stage. This paper introduces a pipe jacking technology with non-over excavation. The data of jacking force and steel pipe stress were recorded and analyzed in the process of pipe jacking. According to field monitoring data and the finite element numerical simulation results, the face resistance and the friction resistance can be obtained by back analysis. And the face resistance obtained is compared with the empirical value. The results show that JMTA and P-K models have practical significance in calculating face resistance F0, while Ma Baosong model underestimates the value of face resistance in silty sand formation. This research can provide a theoretical basis for the selection of jacking force prediction model. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
