摘要:
将有限差分法程序用于可液化土的地震响应分析,采用动力和流体的流固耦合理论分析了振动过程中土体孔隙水压力的产生、扩散与消散,并对液化场地桩-土-结构相互作用体系振动台试验进行了三维数值模拟; 通过与振动台试验数据的对比分析,验证了计算模型的可靠性和合理性。结果表明:采用的方法能较好地模拟可液化土的动力特性,所得结论为液化场地土-结构相互作用体系动力分析提供了参考。
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.
