隧道工程中渗流引起的渗漏问题分析

Analytic Study on Engineering Problems of Seepage in Tunnel Construction

地下工程中的地下水渗漏问题一直是工程中的一大难题。在隧道开挖中,地下水的渗流情况直接影响施工的质量,严重时还将给施工带来灾难。文章详细地分析了隧道工程中地下水渗流的危害、渗流发生的条件,渗流发生的机理,随后提出了设计时要考虑地下水的影响问题,施工过程中要做好防排水工作,后期养护也要密切注意薄弱环节的渗水问题。对不同程度的渗水问题,因地制宜提出了不同的解决方法。最后提出一些目前亟待深入解决的渗水问题。

The problem of water seepage is always the hardest work in underground engineering. The seepage of the tunnel affects directly the construction quality in the tunnel excavation and even causes disasters. At first, this paper analyzes the harm of groundwater seepage, the condition of the seepage generation and the mechanism of seepage. Then, it puts forward that the influence of the groundwater should be included in designs. The water protection and draining should be done during construction. And attention should be paid to the weak part in respect to the seepage during later maintaining. It brings forward different ways of treatment according to different conditions. At last, it puts forward some problems that should be studied and solved at present.
