寒区大断面软岩隧道冻胀渗漏水处治施工技术
|
摘要
为了解决寒冷地区隧道的抗冻、防冻问题,以金盆湾隧道冻胀渗漏水处治工程实例为依托,深入分析渗漏水原因,提出了"排堵结合,以排为主"的隧道渗漏水处治方案,并进行了详细的论述和总结。工程实践结果表明,采取该方案治理后,渗漏水处治效果较好,未再重复发生渗漏。
In order to solve the antifreeze and preventing frostbite problems of the tunnel in cold area,based on the treatment engineering example of Jingpenwan tunnel frost heave leakage,this paper has made a deep analysis on the causes of water leakage,put forward the water leakage treatment scheme which is the combination of drainage and plugging,mainly drainage,and has carried on the detailed elaboration and the summary. The results of engineering practice show that the treatment effect of leakage water is better after adopting this scheme,and no leakage occurs again.
