软土地层中盾构隧道地震反应分析
|
摘要
采用动力有限元──双渐近多向透射边界方法计算了软土地层中盾构隧道的地震响应，分析了洞体参数（包括洞径、埋深及衬砌弹模）对盾构隧道地震响应的影响，得出的规律可为地铁抗震分析提供依据。
Based on dynamic finite element- doubly asymptotic multi - directional transmitting boundary method,the seismic response of shield tunnel in soft soil is calculated. The influence of some parameters such as diameter, depth of tunnel, Young's module of lining, is analyzed. The results can be the basis of seismic analysis of subway.
