Abstract:
Finite differential program was employed to analyze the seismic response of liquefiable soil. Fluid-mechanical coupling method was employed to calculate the generation, diffusion and dissipation of pore water pressure in the soil during vibration process; furthermore, 3-D numerical simulations on shaking table tests of pile-soil-superstructure interaction system in liquefaction field were performed. Through comparing with the data of shaking table tests, the reliability and validation of the calculation model were verified. The results show that the dynamic characteristics of liquefaction soil can be simulated by using this method. The research work can provide references for dynamics analysis of soil-structure interaction system in liquefaction field.
