Abstract:In hydropower engineering,the engineered slopes on both river sides are characteristics of large scale,high and steep geometry,long service life and high stabilization requirement. The design,construction and safe operation of the high-steep rock slopes has been a key technological issue in hydropower projects. Following a literature review,this study discusses the scientific problems associated with the life-cycle safety control on high-steep rock slopes,including the engineering disturbance effects of high-steep slope rock masses in high geostress condition,the mechanisms of high-steep slope deformation and stability evolutions in harsh environment,and their life-cycle performance evaluation and safety control theory,etc. The scientific ideas and technology road map for researches on this topic are presented and some preliminary results are illustrated. A prospect is made for researches on the engineering disturbance effects induced by high-steep slope excavation,reinforcement and seepage control,the time-dependent mechanical properties of high-steep slope rock masses,the interactions among slopes,dams and reservoirs,the mechanisms of slope stability evolution,and the life-cycle performance evaluation and safety control of high-steep rock slopes,etc.
