【摘要】 本文简要叙述了深埋富水地区隧道工程外水压力处理的两种方式,从不同角度分析了两种处理方式的优缺点。根据渗流计算的原理分析了“灌浆封堵”外水压力的作用机理。并结合工程实例,对“以堵为主、堵排结合”渗控措施进行了三维有限元数值仿真分析,得出了工程实用的渗控方案,分析结果可为工程设计施工提供参考。更多还原

【Abstract】 Two methods for treating the high external undergroundwater pressure in deep tunnels are described in this paper.Some advantages and disadvantages are analyzed from different points.According to the permeating theory of the underground water,the principle of preventing the subsurface water draining is put forward for tunnel analyzed.Combined with practical engineering example,3-D nonlinearly finete element simulation are calculated,some suggestions of the construction with similar things are presented.更多还原
