Abstract:
Based on the shaking table test result of the dynamic interaction between soil and subway tunnel in liquefiable soil, a 2-D nonlinear dynamic interaction finite element model is established to simulate the system of soil-tunnel with the platform of ABAQUS. In the finite element model, dynamic viscoplastic model with memorial nested yield surface is used to simulate the dynamic characteristic of soil, while the plastic-damage model is used to simulate the dynamic characteristic of concrete. Corresponding to the test conditions, all the instances are simulated. Compared with the test record, it is proved that both the finite element model and the shaking table test are correct, their results are well identical with each other's and the rules are coincident as well.
