| 摘 要： | 在有效应力动力分析方法基础上，对上海软土地下建筑物进行抗震稳定分析，主要对隧道位于粘性土层和破性土层两种工况进行了详细的计算和分析，计算中分别用唐山、苏南核电站、日本宫城冲和台湾Lotung等几种不同的地震波分别50m和280m的2种不同深度输入，研究上海地层在7度地震作用下，隧道、注浆材料以及隧道附近土层的反应加速度、孔隙水压力及其比值、动剪应力及其比值、最终沉降等，并对上述工况进行较全面的分析和比较。

| Abstract: | Based on the method of dynamic effective stress analysis, the analysis of earthquake resistance of underground construction surrounded by soft soil in Shanghai is presented in this paper. The dynamic response analysis of the tunnel which is located in the soft soil and sand respectively is given as an example. The four different motions,Tangshan, Sunan nuclear power station, Niyasaki gawa and Lotung earthquake motion are used as input motion and two depths of 50 m and 280 m from the soil layer surface are considered as the input base boundare, respectively. The acceleration, pore water pressure and the settlement of the turmel under 7 degree earthquake are given and compared. |
