仰拱及调平层渗漏水处理及隧道路基排水设计优化思考

The Optimization Thoughts on Leakage Treatment and Tunnel Subgrade Drainage Design for the Inverted Arch and Leveling Layer

以某隧道施工过程中出现的仰拱及调平层渗漏水的处理为例,分析问题出现的原因,得出在隧道设计阶段,采用中央排水沟进行隧道排水的必要性,达到提高隧道路面使用耐久的目的。

Taking the inverted arch and leveling layer leakage treatment in a tunnel construction processas an example, this paper analyzed the causes of the problems to conclude the necessity of tunnel drainage usingthe central drainage ditch, which achieved the purpose of improving the tunnel pavement durability in the tunneldesign stage.
