| 摘 要： | 省界隧道在施工期间遇到大型岩溶充填物,隧道拱顶及左侧全为岩溶充填物。岩溶段长度约30m,埋深约100m,在隧道开挖过程中,时逢降雨,岩溶充填物在地表水的作用下下滑,使初期支护严重超载,致使隧道发生坍塌。文中介绍了隧道的病害情况,并提出了综合治理措施。

| Abstract: | There were some large karst fillings in Shengjie Tunnel during the construction.The apex of arch and the left side of the tunnel was filled with karst fillings.The karst fillings were about 30m long and the depth of embedment was about 100m.At the beginning of excavating,it was confronted with raining.Under the influence of the surface water,the karst fillings made the preliminary bracing overload and made the tunnel collapse.The paper introduced the tunnel condition in detail and proposed the comprehensive countermeasures.The practice proved the comprehensive countermeasures are reasonable and safe. |
