摘　　要：通过对高桥电站长隧洞地质勘察实践,对长隧洞勘察方法进行了有益的探索,提出在选线阶段有条件时辅以遥感技术进行地质测绘;在定线阶段,可能涌水段应测地下水位等;在施工阶段,在分析有大的破碎带及岩溶洞穴段、较大的涌水地段时,使用水平超前勘探、预报。这样既能省去不必要的重型勘探(特别是钻孔),赢得勘察进度,又能使地质勘察很好地为设计、施工服务。The valuable probing for the long tunnel geologic reconnaissance has been made through the reconnaissance practice of long tunnel of Gaoqiao hydropower station and it is suggested that the remote sensing technology be used for auxiliary geologic reconnaissance under the permissible condition in the route selection stage. In the route determination stage, the underground water level should be measured for the section where water pouring-out is possible. In the construction stage, for karstic cavern and comparably large water pouring-out section, the pilot horizontal reconnaissance and prediction should be used. These reconnaissance methods can not only omit unnecessary heavy reconnaissance(especially drilling), speed up reconnaissance progress, but also serve well the design and construction.
