摘要我国西南地区大型水电工程普遍面临高陡岩质工程边坡稳定性控制难题，其复杂性与风险性直接关系到工程建设与运行安全。以乌东德水电站工程边坡为典型案例，系统分析了高陡工程边坡地质特征及稳定性控制的关键因素。在此基础上，提出“全过程–全要素–全层次”的系统化治理理念，构建了以安全控制为核心的高陡工程边坡系统治理体系。同时，形成了面向自然边坡与人工边坡稳定性控制的技术方法，并建立自然边坡治理与人工边坡开挖同步推进的控制策略，实现了安全目标与施工进度的协调统一。最后，总结并固化了大型水电工程高陡工程边坡系统化治理项目管理的标准化流程及配套表格。监测结果表明，所提出的系统化治理体系能够有效保证高陡工程边坡的整体稳定性，确保边坡开挖与治理过程安全可控。研究成果可为我国西南地区及类似地质条件下重大水电工程高陡边坡治理提供重要参考。

Abstract：Large-scale hydropower projects in Southwest China typically encounter challenges in maintaining the stability of high-steep rock slopes, with their inherent complexity and associated risks directly affecting construction and operational safety. This study takes the engineered slopes of the Wudongde Hydropower Station as a representative case to systematically investigate the geological characteristics and key factors influencing the stability control of high-steep engineered slopes. Based on this analysis, a systematic treatment concept is proposed, integrating full-process, full-element, and full-level control, leading to the establishment of a comprehensive safety-oriented treatment system for high-steep engineered slopes. Additionally, technical methods for the stability control of both natural and artificial slopes are developed. A coordinated control strategy is formulated to facilitate the synchronous advancement of natural slope treatment and artificial slope excavation, thereby achieving an effective coordination between safety and the construction schedule. Finally, standardized management procedures and supporting documentation for the systematic treatment of high-steep slopes in large-scale hydropower projects are summarized and formalized. The monitoring results indicate that the proposed treatment system effectively ensures the overall stability of high-steep engineered slopes, providing safety and controllability throughout the slope excavation and treatment processes. These findings provide a useful reference for the management of high-steep slopes in major hydropower projects across Southwest China and other regions with similar geological conditions.
