摘要
在隧洞施工过程中,造成塌方的因素很多很复杂,地质因素、设计因素、施工因素、管理因素等都是有可能造成隧洞塌方的原因,不同项目的水工隧洞,由于所处地域不同,工程地质条件、围岩类别、地下水等差别很大,针对具体塌方问题采取有针对性的处理措施是解决隧洞塌方的有效处理方法。本文结合隧洞塌方处理的工程实例,分析了隧洞塌方产生的原因,在普氏压力拱理论分析的基础上结合长河电站引水隧洞塌方问题,提出了有针对性的处理方案,为类似工程事故的处理提供了借鉴的经验。
In the process of tunnel construction,there are many complex factors which may cause the collapse of the tunnel,such as geological factors,design factors,construction factors,manage factors,etc..There are huge differences between different diversion tunnels,such as engeneering geology conditions,the types of wall rock,and underground water.The effective measures to handle the collapse problem is to use pertinence treament to the specific situation.This paper consults the living example measures of tunnel collapse,and analyzes the factors of tunnel collapse.On the base of PU pressure theroy,this papers analyze the problems of the tunnel collapse of Changhe hydrapower station,and put forward some pertinence treament schemes,so as to support some salutory lessons for dealing with similar engeneer accident.
