摘  要:高陡边坡变形与稳定性分析是水利水电工程建设与运行的关键技术难题。近二十年来,我国建设了一批大型水利水电工程,成功解决了许多高坝大库的关键技术难题,在库坝高陡边坡全生命周期性能演化与安全控制方面取得了显著进展。本文紧扣高陡边坡变形和稳定性演化这一主题,以西南水电工程高陡边坡性能评价为研究主线,阐述了高陡边坡稳定性影响因素和破坏模式、稳定性评价与变形分析方法、渗流分析与控制等研究进展,重点聚焦严格三维极限平衡方法、修正Hoek-Bray楔形体法、刚体弹簧法、基于监测数据的参数反演方法以及边坡渗流分析等方面的研究成果,论述了水电工程高陡边坡全生命周期变形与稳定性演化分析的学术思路与技术路线,讨论了未来面临的一些挑战性难题。The deformation and stability analysis of high steep slopes is a key technical problem in the construction and operation of hydropower projects.Over the past two decades,China has built a large number of large-scale water conservancy and hydropower projects.Many key technical problems of high dams and large reservoirs have been solved successfully,and remarkable progress has been achieved in the life cycle performance evolution and safety control of high,steep slopes of reservoirs.This paper takes the performance evaluation of high steep slopes in the southwest hydropower projects as the main research line,and focuses on the deformation and stability evolution of high steep slopes.We examine the research progress in determining the influencing factors of stability and failure modes of high steep slopes,stability evaluation and deformation analysis methods,seepage analysis,and safety control.The latest researches are discussed in detail on the strict three-dimensional limit equilibrium method,modified Hoek-Bray wedge method,rigid body spring method,parameter inversion method based on monitoring data,and slope seepage analysis.We also discuss the academic thinking and technical route and certain future challenges to the life-cycle deformation and stability evolution analysis of high steep slopes in hydropower engineering.
