| 摘 要： | 文中针对某山岭隧道施工过程中掌子面出现地下水突发大量涌出的不良地质现象,从隧址区工程地质及水文地质条件、洞内涌水量与地表水体水位的联系、洞内掌子面地质条件、隧址地表山塘地质条件等角度进行综合分析,得出断层破碎带及其影响带之间的连通使得山塘与隧道涌水段(RK5+917~RK5+903)具有密切的水力联系,是突发涌水的主要地质成因。

| Abstract: | To counter the phenomenon of sudden gushing water in the mountain tunnel construction stage, after comprehensive analysis of engineering geologic and hydrogeological condition of the tunnel area, relations between quantity of gushed water in the tunnel and the water level of the surface wateL geologic condition of the tunnel face and the pond in the tunnel area, we conclude that the connectivity of the fault fracture zones and its influence zones brings the closely hydraulic connection between the pond and the gushing water tunnel（RK5＋917-RK5＋903）, which is the main geologic cause of the sudden gushing water. |
