摘要
采用弹塑性本构关系和摩尔库伦屈服准则,应用八结点平面等参单元,对某城市地铁不同埋深的三个典型断面的区间隧道及其周围土体这一结构复合系统进行动力有限元分析,揭示出不同埋深情况下地铁隧道结构的工作状态,为地铁选线及结构设计提供依据。
Adopting the finite element method,nonlinear stress-strain relationship of material and Mohr-Coulomb yield criteria,with the 8-node plane parametric finite element,dynamic responses of complex systems which are composed of one of three typical sections of a tunnel with different burial depths as well as the surrownding soil body are analygzed.The different working states of the subway tunnel structure with different burial depths are revealed.It provide basis for subway tunnel design and subway line-trend choice.
