摘要

根据上海地区典型土层的力学特性,拟合得到简化亚塑性边界面模型的动力计算参数,同时考虑流、固耦合以及地震多向作用的耦合,以 San Fernando1971 年地震记录的加速度时程曲线为输入地震波,对上海 280 m 深典型地层的地震反应进行了分析,得到了有意义的结果。
Based on the mechanical behaviors of representative soil layer in Shanghai, the simplified bounding surface hypoplasticity model parameters are calibrated by curve fitting. Using the acceleration time histories records for SAN FERNANDO earthquake in 1971 as the input motions, the seismic responses of Shanghai horizontal soil layer of depth 280 m are studied; the coupling between soil skeleton and fluid deformation, as well as the motions in three directions are taken into consideration in computations simultaneously, some results are useful.
