摘要
渗水病害对公路隧道的正常运营有极大的危害,关于隧道渗水的病害类型、产生原因和治理方法的研究也较多.对甘肃某在建隧道进口浅埋段二衬严重渗水检测和勘察的情况进行了分析,得出了其产生原因为周边地形地质水文环境、隧道的设计和施工中的不重视与不规范.针对施工缝渗水采取了凿槽引排和注浆的治理措施,用凿槽引排治理线状渗水;凿洞堵漏的方法治理点状渗水.通过对渗水治理前后的对比,可以看出治理效果较好,对于今后的类似隧道渗水病害治理具有一定的参考价值.
Water leakage diseases in tunnel are of great harm on the normal operation of highway tunnel, plenty of study about different types,reasons and treatment technology of diseases water leakage in tunnel. It analyzed according to the diseases detection of water leakage of secondary lining for a building tunnel in shallow-buried Section in Gansu Province, to obtain some results of the surrounding topography, geological environment and hydrology, not reasonable of the design about the tunnel, and not standard during construction. It uses of some treatment methods of taking a gouge and grouting for construction joint, gouge guide water for water leakage of linear, chisel a hole and plugging for dot. By cQmparison of leakage before and after treatment, it obtains a good control effect, which can serve as reference ~：or water leakage prevention of the future similar tunnel construction.
