摘　　要：沐若水电站引水隧洞采用两机一洞平行布置,隧洞具有埋深大、洞线长、软岩、高内水压、地下水丰富等特点。在工程设计与施工中,针对隧洞围岩稳定、衬砌设计、强地下水处理等问题,通过采用工程类比、理论研究、数值分析等方法,选择了合理的隧洞布置与结构设计方案,并采取有效的工程措施,减小外水压力,提高了工程的安全性,保证了工程顺利实施。The parallel layout of ＂a water diversion tunnel for two turbine units＂ is adopted for Murum Hydropower Station; the diversion tunnel has the characteristics of deep burying, long tunnel line, soft surrounding rock, high hydraulic pressure and a- bundant groundwater. In view of stability of tunnel surrounding rock, lining design and high groundwater treatment, the appropri- ate design solutions for tunnel layout and structures are selected and the engineering measures are also adopted by means of the engineering analogy, theoretical research and numerical analysis. Some effective engineering measures were taken to release out- side water pressure, improve the engineering safety and ensure the smooth construction of the project.
