摘要
在二维有效应力动力反应分析方法基础上 ,提出一种考虑行进波和应力差分量的计算方法 ,并以上海地铁一号线隧道为例 ,对地铁隧道处于粘性土层和砂性土层两种工况 ,分别按不同断面、不同地震烈度、不同的地震波输入方向 ,以及考虑不同应力差分量的剪应力计算方法等几种情况进行计算分析 ,得出一些有意义的结论。
Based on the procedure for 2-D effective stress dynamic response analysis, a new method considering both the traveling waves and the stress difference is presented. Detailed analyses on the tunnel 1# of Shanghai subway surrounded by clay and sand respectively is given as an example of the proposed method. In each case, different sections, different directions of traveling waves and different methods to calculate the shear stress are mainly considered. Through the calculation and analysis for different situation, the significant results are obtained.
