摘　　要：在建的金沙江乌东德水电站坝址区地质条件复杂,存在一系列制约或影响工程建设的重大地质问题,特别是坝址下游的金坪子滑坡的稳定性,关乎到该水电工程的成败。为此,对该工程的关键或重大地质问题进行了深入、系统的地质勘察和科学论证。认为,金坪子滑坡不是一个具有统一滑面的滑坡,不影响水电站的建设。地质勘察还确定了落雪组第三段岩体在右岸的空间分布位置,研究了超高陡自然边坡的稳定性和河床深厚覆盖层的特性,以及合适的大坝混凝土骨料料源。其经验可供类似工程参考。The geological condition at the dam site of Wudongde Hydropower Station on Jinsha River is complicated, especially the stability of Jinpingzi landslide, which concerns the smooth construction of the project. Therefore, the key or important geolog- ical issues were deeply and systematically investigated and scientifically demonstrated. The demonstration shows that no integral sliding surface is existed in Jinpingzi landslide and it has no influence on the project construction. By geological survey, the spa- tial distribution of the third rock body of Luoxue Formation （ especially for the right bank）, the stability of super high - steep nat- ural slope, the characteristics of the thick overburden layer and the suitable material field （Shiqi） are studied.
