摘　　要：老挝南欧江五级电站枢纽布置十分紧凑,施工导流、泄洪消能、引水发电等主要建筑均集中于坝身和坝后,建筑物间关系十分复杂,设计和施工均有较大难度;坝址出露地层为石炭系下统(C1)和第四系(Q),全、强风化层较厚,弱风化埋深较大,边坡开挖高度大,稳定性差,处理难度大。介绍了在地形条件十分有限和地质条件相对复杂条件下枢纽布置特点和主要建筑物设计,以及主要技术问题的研究和处理措施。The project layout of Nam Ou 5 Hydropower Station is very compact, that all of main structures, including construction diversion, flood discharge and energy dissipation, water intake and power generation, are arranged in dam body or dam-toe. The relationship between structures is very complex, so the design and construction are also very difficult. The rock layers in the dam site are Carboniferous system（ C1） and Quaternary（ Q）, in which the full and strong weathered layers are thicker and the weakly weathered layers are deeply buried, so the slope excavation height is high, the stability is poor and the treatment is also difficult. The characteristics of project layout and the design of main structures are introduced and the main technical issues and its treatment measures are also presented.
