摘要
文章介绍了隧道施工中遇到的剪张裂缝和古岩溶特殊地质现象,阐述其成因、施工影响以及富水环境下防治涌水突砂的施工技术措施,提出带水作业三个条件及配套处理措施,以期能为今后类似工程安全施工提供借鉴参考。
This paper introduces the shear tensile cracks and palaeo rock solution encountered in tunnel construction of special geological phenomenon, explains its causes, influence of construction and water environment treatment of prevention waterinflow and inrushing of sand construction technical measures are put forward, working with water in three conditions and supporting measures, hoping to provide a reference for the similar engineering construction safety.
