摘　　要：南昆线草庵隧道在施工过程中软弱围岩段遇到多次大涌水,造成大量坍塌,并导致329m既有衬砌开裂、变形、致使施工多次受阻。本文对涌水段工程地质及水文地质、围岩深孔预注装、衬砌裂损整治做一个比较全面的介绍。During excavation of the poor ground section of Caoan Tunnel on Nankun Railway , water inflow occurred for many times , which resulted in tunnel collapse , lining cracking and displacement. This paper describes the engineering geological and hydrogeological conditions, deep 梙ole grouting and rehabilitation of crack lining.
