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.

Key words： slope engineering high-steep rock slopes life-cycle performance evolution safety control
