摘　　要：以巴基斯坦Mohmand水电站进水口为依托,其边坡具有倾角陡、高差大等典型特征,为解决进水口高陡边坡施工面临的结构安全问题,提出“台阶开挖法”与“全面浅层支护联合局部深层支护”相结合的施工技术。通过工程实践表明该施工技术切实可行,能有效规避边坡失稳风险。This paper is based on the water intake of Mohmand Hydropower Station in Pakistan,where the slope has typical characteristics such as steep inclination and large elevation difference.To address the structural safety issues faced by the construction of high and steep slopes at the water intake,a construction technology combining"bench excavation method"with"comprehensive shallow support combined with local deep support"is proposed.Practice has shown that this construction technology is feasible and can effectively avoid the risk of slope instability.
