【摘要】 基于土-结构相互作用模型,利用粘-弹性边界条件,运用时程分析方法研究浅埋偏压隧道在水平地震、垂直地震以及45°方向作用下的全时程动力反应规律。对围岩和衬砌受力、注浆锚固范围等隧道工程特性进行分析研究,以期为浅埋偏压隧道抗减震设计提供一定参考。更多还原

【Abstract】 Based on soil-structure interaction model and by means of viscosity-elasticity boundary condition,this paper adopts time course analysis method to investigate the full-time dynamic response rule of shallow burying biased tunnel under effect of horizontal earthquake,vertical earthquake and 45° direction.The paper also analyzes and studies tunnel project properties such as wall rock,force on lining,grouting and anchoring range in the hope of providing certain reference for seismic design of hallow burying tunnel.更多还原
