摘　　要：大垭口隧道位于万县市以北22km万县与开县交界处,全长1475m,单洞双车道。由于地质条件等原因,隧道产生开裂、漏水等现象,严重危及行车安全,需要进行整治。病害整治的方法为:对隧道衬砌裂缝进行环氧树脂嵌补和注浆,对衬砌薄弱环节进行套衬补强,对地下水则用高分子丙凝注浆、水泥-水玻璃注浆、凿槽引排等措施进行治理。Dayakou tunnel, a one-tube tunnel of two lanes with a total length of 1475m, is located 22km from Wanxian city in the north where Wanxian is bounded by Kaixian. Due to geological conditions and some other reasons, cracks and water leakage occur in the tunnel, which severely jeopardizes the safety of the running vehicles. Therefore the diseases of the tunnel need to be treated. The method of the disease treatment is as follows: epoxy resin caulking and grouting are performed against the cracks of the tunnel lining, supplementary reinforcing inner lining is performed for the weak sections of the tunnel lining and measures, such as macromolicule acrylamide grouting, cement-glass grouting, water releasing by cutting channels, are taken to cope with the ground water.
