随着我国国民经济的发展及对工程建设环保要求的逐步提高,隧道工程在公路、铁路及市政工程中的量越来越大。由于隧道工程为地下工程,且所处地理、地质及环境条件复杂多变,加之由于设计、施工及运营管理方面的原因常造成隧道渗漏水,这已经成为影响我国各类隧道正常运营的重要因素之一。本文以高速公路隧道为例,简要介绍隧道渗漏水的成因,分析隧道渗漏水对衬砌结构安全性的影响,指出了隧道渗漏水对衬砌结构的危害及处治基本方案。
With the development of our national economy and the gradual improvement of environmental protection requirements for construction projects, the amount of tunneling projects in roads, railways and municipal engineering projects has been growing. Due to the fact that the tunneling works are underground works and the geological, geological and environmental conditions are complex and changeable, and the tunnel seeping water often results from the design, construction and operation management, it has become an important factor that affects the normal operation of various types of tunnels in our country One of the factors. This paper takes highway tunnel as an example to briefly introduce the cause of tunnel seepage water, analyzes the influence of seepage water of tunnel on the safety of lining structure, and points out the harm of tunnel seepage water to lining structure and the basic plan of treatment.
