摘要

研究了一些对地铁隧道抗震稳定有较大影响的因素。例如

地铁隧道的整体平均容重和地铁隧道的埋深

尽管它们对地基的孔隙水压力发展影响不大

但却对地铁隧道的震后残余变形影响相当显著。还有

砂性土中粘性土的含量多少对砂性土的动力行为有直接而显著的影响。最后

从能量的角度分析了输入不同地震波的地铁地基土层动力反应的差异。

Abstract

Some factors affecting underground tunnel stability against earthquake are studied in this paper.The results obtained showed that the average unit weight and embedded depth of subway tunnel influencesmarkedly the post-earthquake residual deformation of subway tunnel

though has a little effect on pore wa-ter pressure. Clay content in sandy soil directly and evidently influences dynamical conduct of sandy soil inthe foundation. Finally it is explored from the point of view of energy that why inputting different earth-quake waves could result in marked distinction in dynamical reaction of subway foundation.
