摘要
隧道渗漏水是一种常见的病害,如果不进行有效的治理,将严重影响隧道的正常运营.通过对甘肃某隧道进口浅埋段的渗水情况及周边水文地质环境进行调查分析,认为当地特殊的地质条件、隧道施工工序和防排水措施是导致其渗漏水的主要原因.结合现有的渗漏水治理技术与现场实际情况,探索出以下治理措施:对于渗水量小的点状渗水采取以堵为原则,运用凿洞堵漏治理;渗水量较大的线状渗水采取以排为原则,运用凿槽引排治理;渗水量严重的施工缝采取堵排结合的原则,运用围岩和衬砌注浆与凿槽引排治理.实践表明治理效果较好,对公路隧道二衬渗漏水的防治具有一定的参考价值.
Water leakage in tunnel is a common disease; if no effective treatment technology, it will have a prodigious badly impact during normal operation. According analysis of field survey of water leakage situation and surrounding hydrogeology about the shallow-buried section of the tunnel in Gansu province, it is consid- ered that the major causation are the local special geological conditions, tunnel construction process and water proof and drainage measures. Combining currently entire treatment technology of water leakage disease and the actual situation, we explore the following measures： The principle for little punctiform water seepage is stop influent, useing the method of hole plugging to dispose; the principle for biggish threadiness water seep- age is to guide discharge, useing the method of gouging guide discharge; the principle for serious water seep- age of construction joint should combine stop and discharge, useing the method of grouting and gouting guide discharge. Practice indicates that the control effect is better, it has a certain reference value for some highway tunnel water leakage at the concrete lining surface.
