Abstract:

A model structure of three-story and three-span subway station at liquefiable ground was analyzed considering the far field and the near field ground motion based on a metro station in Nanjing. Problems existed in the large-scale shaking table model test were discussed and the relevant solutions were proposed, which included the development of flexible box and dynamic data acquisition system, as well as the determination of structure and soil's similarity criterion. Parameters such as acceleration, horizontal displacement, strain response of the station, and the pore water pressure, acceleration, seismic subsidence of soil and dynamic soil pressure on the sidewall were measured. Results show that the soil under near field and far field ground motion presents an amplification phenomenon with low frequency. However, the degree of amplification effect and the frequency range appear to be a great difference for the distinction of spectrum characteristics between near field and far field. The fundamental frequency of shallow soil is close to the dominant frequency of the motion when it comes to the far field motion; the soil's amplification effect seems to be significant. The existence of the underground structure has remarkable influence on the seismic dynamic characteristics of adjacent soil.
