地铁车站渗漏水病害的设计因素分析

Analysis of Design Factors Causing Leakage of Metro Station

随着我国经济的不断发展,交通压力不断增大,轨道交通随之蓬勃发展。地铁作为城市轨道交通的一部分,可以极大缓解市内交通压力,修建地铁已经是各个大城市缓解路面交通压力的新途径。随着地铁工程数量与规模不断扩大,随之而来的问题也不断浮现。地铁车站作为地下枢纽,人流量极大,安全问题必须得到高度重视。明挖地铁车站在建设过程中会产生渗漏水问题,导致车站底板积水、结构开裂与溶蚀等病害,严重影响地铁车站结构的安全性。为此,文章通过详细分析地铁车站结构外防水层设计、车站结构缝处防水设计以及其他设计方面存在的不足,阐述了车站结构设计因素引起渗漏水病害的作用机理与发展过程,为地下工程渗漏水病害处理提供了重要的理论参考。

With the continuous development of China's economy and the increasing traffic pressure,rail transit is booming.As a part of urban rail transit,subway can greatly alleviate the traffic pressure in the city.The construction of subway has become a new way to alleviate traffic in major cities.However,with the increasing number and scale of subway projects,the problems in the construction are more and more prominent.As an underground hub,subway station plays an important role in subway engineering.In the construction process of open cut metro station,there will be water leakage,which will lead to water accumulation,structural cracking,corrosion and other diseases of the station floor,and seriously affect the safety of the subway station structure.Therefore,through the detailed analysis of the shortcomings in the design of waterproof layer outside the structure of metro station,the waterproof design at the structural joints of the station and other design aspects,this paper expounds the mechanism and development process of the leakage disease caused by the structural design factors of the station,which provides an important theoretical reference for the treatment of the leakage disease of underground engineering.
