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有渗透变形稳定问题,对坝基的工程地质条件影响极大。根据软弱岩带的工程地质特性,对渗透变形稳定问题进行了专门的现场试验研究,并结合试验成果对构造软弱岩带的渗透稳定性进行了初步分析,提出了相应的工程处理措施。The engineering geological conditions of the Nuozhadu hydropower project are very complex, especially for right-bank weakened rock zone. The zone has seepage deformation problems, which produces huge effect on the engineering geological conditions of dam foundation. This paper, based on the engineering geological characteristic of weakened rock zone, describes the special field tests on the stability of seepage deformation. In combination with the test results, it analyzes preliminarily the seepage stability of weak rock zone and puts forward the corresponding engineering treatment measures.
