以有效应力原理的有限元计算分析为主、铁路工程抗震设计规范及室内动三轴实验为辅 ,对修建在粉土或粉细砂层中的盾构隧道进行了两种不同埋深情况下的液化分析 ,得出了埋深不同液化区出现区域不同的结论 ,并提出隧道抗液化的合理埋深
Based on the finite element analysis of effective stress principle, supplemented by seismic design code of railway engineering and indoor dynamic triaxial experiment, the shield tunnel built in silt or silty sand is under two different burial depths Liquefaction analysis obtained different depths of different liquefaction zone appeared in the region of the conclusion and proposed a reasonable anti-liquefaction of the tunnel depth
