金沙江乌东德水电站左岸尾水出口边坡为陡倾顺向坡，边坡下部顺向坡切脚的同时尾水洞开挖亦为边坡变形提供了条件。为评价该顺向坡的稳定性，通过工程地质调查、变形监测、物探检测相结合的研究手段，对边坡稳定性分层次进行了综合研究，查明了边坡变形的原因与机理。研究结果可为设计方案的制定提供依据，为类似边坡稳定性的研究工作提供了宝贵的经验。

The slope at tailrace outlet on left bank of Wudongde Hydropower Station is steep consequent slope. The corner cut of the lower part of the consequent slope together with the excavation of tailrace create favorable conditions for slope deformation. In order to evaluate the stability of the slope, the comprehensive research is conducted hierarchically through engineering geolog-ical survey, deformation monitoring and geophysical detection. And the causes and mechanism for slope deformation are re-vealed, which provides basis for drawing up the design scheme.
