摘　　要：在全面搜集重庆地区现役187座高速公路营运隧道的基础上,针对目前出现渗漏水病害的66座隧道进行了调研,依据对隧道区域分布、隧道长度、渗漏水病害的严重程度等综合因素的考虑,选取了14座典型渗漏水病害隧道作为研究对象,分别就裂缝的几何形态和闭合度,渗漏水的形式以及渗漏部位进行了分类统计分析,并就地下水、衬砌裂缝以及渗漏水之间的关联性进行了探讨,最后根据对隧道地勘、设计、施工等资料的统计,结合现场调研的情况,认为导致重庆地区现役高速公路隧道渗漏水病害的原因主要有4点:不良地质条件、施工因素、防排水设施以及地下水的腐蚀性等。研究成果对于开展重庆地区公路隧道渗漏水病害的防治与营运期间的维护具有重要的现实意义和参考价值,同时也可为其他地区或全国公路隧道渗漏水病害的统计分析提供参考。Based on comprehensive collection of 187 operating expressway tunnels in Chongqing area, 66 tunnels with leakage diseases are investigated. Considering comprehensive factors such as the tunnel regional distribution, the length of tunnel, and the severity of leakage diseases, 14 typical tunnels with leakage diseases are selected as research object. Statistical analyses in classification are performed in terms of geometric shape and closure of cracks and the form and location of leakage diseases. The relevance among underground water, lining cracks and leakage water are investigated. Finally, based on the statistics data of geological exploration, designation and construction, and taking account of in-situ investigation, the main 4 factors that result in the leakage diseases in operating expressway tunnel in Chongqing area are drawn as below： poor geological conditions, construction factors, incomplete drainage facility and corrosion of underground water. The research results have realistic significance and reference value in the prevention and control of leakage diseases and tunnel maintenance during tunnel operation period in Chongqing area, and can provide a reference for other regional or national highwav tunnels with leakage diseases as well.
