摘要

岩溶是石灰岩地区地下水作用的过程与结果，是隧道洞室所面临的不良地质现象之一。结合岩溶系统区域内大型地下电站的建设，采用显式有限差分法模拟地下厂房的施工开挖，分析了岩溶系统对地下厂房洞室群围岩稳定性的影响，
评价了溶洞回填处理措施的加固效果。

Abstract

Karst is a process and result of groundwater geologic function and one of bad geological phenomena to tunnel grotto construction. In combination with the construction of the large underground power plants in a karst region, the stability of surrounding rock mass is studied with 3D explicit fi nite difference method.This paper analyzes the influence of surrounding rock mass stability with karst on underground power houses, and evaluates the reinforcing effect of underground grotto group with filling up.
