摘要
郭大寨水库营盘山隧洞出口段边挖边衬的施工案例,在一定程度上解决了不良地质隧洞段在初期支护后发生变形的问题,并加快了施工进度,节约了工期,为同类工程提供借鉴。
The construction case of lining while excavation at the exit section of Yingpanshan tunnel in Guodazhai reservoir solved the problem of deformation after initial support in bad geological tunnel section to some extent, and accelerated the construction progress and saved the construction period. Hoping to provide reference for similar projects.
