南果河电站厂区在施工过程中．由于开挖面暴露后未及时衬砌．因而在１９８６年、１９８７年雨季，先后发生了两次滑坡．沿体总量达２５０００ｍ３．本文论述了南果河电站厂区枢纽的工程地质概况．分析了滑坡发生的原因及整治过程．并提出了应引以为鉴的经验教训．
Nanoguohe power plant area in the construction process. As the excavated surface after the lining is not promptly exposed. Thus in 1986, the rainy season in 1987, there have been two landslides. The total body along the body of up to 25000m3. This article discusses the engineering geology of Nanoguohe power plant hub. The reasons for the landslide and the remediation process are analyzed. And put forward lessons that should be drawn from the experience.
