摘　　要：糯扎渡水电站工程地质条件复杂,尤其是坝址右岸存在的构造软弱岩带,对坝基的工程地质条件影响极大,该软弱岩带存在渗透变形问题。文章针对渗透变形稳定问题进行了专门的现场试验研究,并对试验过程、方法、要求和成果进行了系统的分析论述,为本工程水工建筑物布置和右岸坝基防渗处理提供了重要依据,同时也希望这一试验方法能为其它工程解决类似问题有所帮助。Nuozhadu hydropower project is located in an area where the engineering geology conditions are rather complicated, and in particular a structural soft rock zone exists in the right bank of the damsite, which have a great impact on the engineering geological conditions of the dam foundation. The soft rock zone would cause seepage and deformation problem. The authors have made special field test and study of the stability against seepage and deformation. The paper has systematically analyzed and expounded the test process, method, requirement and results, thus providing important basis for layout of the hydraulic structures and the right bank dam foundation seepage control treatment. It is hoped that this test method could help solve the similar problems of other projects.
