Abstract：There is rich hydroelectric resource in Southwest China with high mountains and deep canyons，and many hydropower projects with high dams and large reservoirs are located in this area. Due to specific topographic and geological condition，stability of the complex high slopes in these projects has become one of the key technical problems which restrict the effective development of hydroelectric resource and project construction. Taking the hydropower project practice in Southwest China into consideration and combining the corresponding research achievements，main technical features and key problems of slope engineering have been summarized and analyzed，and research approaches and contents of rock engineering has been brought forward. On this basis，some new ideas and methods such as genesis of deep fissures in slope，slope structure，parameter values，safety criterion，reinforcement design method，feedback analysis，etc. have been put forward from several aspects including geological condition，slope engineering design theory，and construction process controlling，etc. These methods and theories have been successfully applied in the design and construction of slopes in hydropower projects. Particularly，the extremely high slopes in Jinping I project(530 m) and Dagangshan project(420 m) consisting of deep unloading and relaxation rock masses have been successfully constructed. These research achievements bear beneficial reference significance to the investigation and design of slope engineering and the development of rock mechanics.
