岩溶发育地区隧道溶洞处治方法

Treatment Method for Tunnel Caves in Karst Development Areas

岩溶发育地区隧道溶洞的处治方法影响隧道后期的运营寿命和安全。文章分析了溶洞的形成机理及其对隧道施工的影响,阐述了隧道溶洞的处治原则,并以广西河池至百色高速公路项目丘莫隧道和梁家隧道溶洞处治为例,介绍了隧道溶洞处治方法,为相似岩溶地质条件下的隧道施工提供参考。

The treatment method of tunnel caves in karst development areas affects the operational life and safety of tunnels in the later period.This article analyzed the formation mechanism of karst caves and its influence on tunnel construction,described the treatment principle of tunnel karst caverns,then,taking the cave treatment of Qiumo tunnel and Liangjia Tunnel in Guangxi Hechi-Baise Expressway project as the example,it introduced the tunnel karst cave treatment method,which can provide reference for tunnel construction under similar karst geological conditions.
