摘　　要：铁峰山2号隧道为万州—开县高速公路的控制性工程,隧道埋深大,工程地质条件复杂,施工过程中地质病害频繁发生,为了预报施工开挖面前方围岩的水文工程地质条件,在地表沿隧道轴线采用长排列、大功率供电的高密度电法系统进行了视电阻率成像探测,探测成果起到了超前预报的目的,指导施工单位提前采取科学、合理的预防措施,减少了塌方、涌水等工程病害的发生。No. 2 Tiefengshan Tunnel is a crucial project in the Wan - Kai highway. The tunnel＇s buried depth is big and the engineering geological conditions are so complex that geological disasters were happened frequently in the constructing. In order to predict the engineering and hydro -geological conditions, we position along the tunnel alignment/axis on the surface with a long array and super power - supply high density electrical resistance exploration system to prevent engineering accidents from occurrence and to reduce mudflow and water gushing, which will provide the construction areas with scientific and reliable grounds.
