摘要

摘要: 在室内软土动力试验和有限元有效应力动力分析方法的基础上，引进了可靠度理论，提出了考虑土-结构相互作用的软土地层中地下建筑物抗震稳定可靠性分析的方法，考虑7度地震烈度时不同软弱土层对地下建筑物抗震稳定的影响，选用多条基岩强震地震记录曲线对典型上海地铁车站进行分析。计算内容涉及车站结构和周围土体的动应力，周围土体的孔隙水压力、震陷及车站结构和周围土体的动力可靠度，所得到的计算与分析结果在理论上提高了对软土地层中地下建筑物抗震稳定性分析的水平，为上海软土地层中地铁车站抗震设计提供了依据。

Abstract: Based on the results of cyclic traxial test, it is presented that an analysis of earthquake resistance of several subway stations which are located in sandy soils and clayey soils in Shanghai.The method of FE dynamic effective stress analysis and reliability analysis is used in the analysis.In order to consider the influence of input earthquake motion, six different recorded earthquake motions selected from both home and aboard are used in the calculations.The results of dynamic response analysis, include the dynamic stresses of subway stations and surrounding soils, pore water pressures and settlements of surrounding soils.The dynamic reliability of subway and surrounding soil is also given.The results of the analysis improve the seismic analysis level of the subway stations surrounded by soft soil, and it is helpful for the aseismic design of underground structures.
