摘　　要：针对沐若电站厂区存在边坡强风化层厚、岩性较差、地下水丰富等不利地质条件。在开挖支护设计过程中,根据施工期和运行期的不同特点和要求,将初期支护与后期加固相结合,采取了挂网锚喷支护、锚筋桩、格构梁和边坡排水系统等措施。基于现场勘查和地质资料以及安全监测资料分析成果,及时修改和调整了边坡加固设计,保证了边坡稳定。工程实践表明,所采取的加固和排水措施技术可靠、经济合理。The geological condition of slope near powerhouse of Murum Hydropower Station is unfavorable, such as thick and strong weath- ered layer with poor lithology and rich groundwater. In the design process of excavation and supporting, according to different characteristics in construction and operation period, with a overall consideration on initial support and later reinforcement, the measures such as bolting shotcrete with wire mesh, anchor bar pile, lattice beam and slope drainage system were adopted. The slope design was adjusted according to the in - situ survey and geology data and safety monitoring results, which ensured the stability of the slope. The engineering practice showed that the reinforcement and drainage measures were technically reliabl~ and economical.
