实例分析黄土公路隧道渗漏水处治技术

对于黄土公路隧道,渗漏水的防治是重要内容,隧道内发生渗漏水会造成黄土围岩的软化,引发变形,影响行车安全。常规黄土公路隧道渗漏水治理是在混凝土衬砌内部凿槽嵌补,将衬砌后的水引出。但是黄土隧道有其特殊性,大量排水容易引发地下水平衡问题。所以,黄土隧道渗漏水的治理需要采取针对性措施,对于新建隧道以防为主,而旧隧道以堵为主。本文通过某案例分析黄土公路隧道渗漏水处治技术,希望对类似工程有所帮助。

Case analysis of treatment technology of water leakage in loess highway tunnel

For the loess highway tunnel,the prevention and control of water leakage is one of the important contents.Water leakage in the tunnel can cause the softening of loess surrounding rock,which leads to deformation and affects the safety of driving.The conventional loess highway tunnel leakage treatment is to excavate and inlay in the concrete lining and draw out the water.However,the loess tunnel has its particularity and a large amount of drainage is easy to cause the problem of groundwater balance.Therefore,the treatment of water leakage in loess tunnel needs to take targeted measures,such as prevention for the new tunnel and blocking for the old tunnel.This paper mainly analyzes the technical aspects of water leakage treatment of loess highway tunnel through a case,hoping to be helpful to similar engineering.
