高寒地区隧道渗漏水病害成因及其处治对策

Tunnel seepage cause disease and its treatment countermeasure in alpine area

在春融季节,高寒地区隧道易出现衬砌渗漏、路面涌水等病害,并诱发隧道衬砌拱顶挂冰、边墙冰柱和路面结冰等冻害。对内蒙古博牙高速兴安岭隧道和扎敦河隧道的病害进行现场调查发现,兴安岭隧道的病害主要为施工缝漏水和挂冰;扎敦河隧道的病害主要为施工缝漏水和路面冒水。综合考虑隧道围岩条件、地下水补给、地形地貌等因素,深入分析病害产生原因,采取注水泥浆、注堵漏剂、设置引流槽、路面打孔、引排地表水等方法综合治理隧道渗漏水,取得了良好的效果,为高寒隧道渗漏水治理提供参考。

In spring, easy to appear tunnel disease such as lining leakage and road surface burst in alpine area, and induce tunnel lining vault ice, icicles and icy pavement. Field investigation on disease of Xing＇anling tunnel of Boketu - Yakeshi highway in Inner Mongolia and Zadunhe tunnel show that the disease of Xing^mling tunnel mainly for construction joint leakage and hanging ice; the disease of Zadunhe tunnel mainly for construction joint leakage and road surface water. Considering the tunnel surrounding rock conditions, groundwater recharge, topography and other factors, in - depth analysis of causes of disease, comprehensive control of tunnel leakage with method such as cement injection, injection plugging agent, setting up drainage trough, punch, guiding surface water, achieved good effect, provide reference for tunnel seepage control in alpine area.
