摘　　要：渗漏是隧道的常见病害,其不仅降低衬砌混凝土的耐久性,而且恶化隧道内环境,影响洞内设施的性能和寿命,并给维修管理带来困难,防渗漏水已成为重要的问题。针对蓝小汽车专用公路牧护关隧道渗漏水病害现状,进行了实地详细调查,分析了病害的成因,进而提出了该隧道防排水系统的治理方案和施工工艺及要求,可为类似隧道病害治理提供经验借鉴。Seepage water in tunnel is a kind of disease, not only reduces endurance of lining concrete, but also worsens environment in the tunnel, influences properties, life of installations in the tunnel, and brings about difficulties for maintenance and management.Based on field method, distress of waterproof and drainage system for the road tunnel is investigated. The reasons of distress are also analyzed. Based on the analysis results, treatment method and emphasis of construction technology are put forward. The treatment scheme is feasible, and can be used to the similar distress road tunnel.
