摘要: 杨房沟水电站坝址河谷狭窄,两岸边坡高达500~600 m,危岩体众多,近坝区分布有大型崩坡积体和泥石流沟。杨房沟水电站枢纽布置十分紧凑,建筑物包括混凝土双曲拱坝及坝身表、中孔和坝后水垫塘及二道坝,引水发电系统布置在河道左岸山体内。通过积极开展动态设计和科技创新,工程建设进展顺利。在危岩体分类及处理、地下洞室和边坡支护动态设计、拱坝体形和泄洪消能优化、崩坡积治理等方面取得了较为丰富的经验。相关经验可供其他水电站枢纽优化设计参考。

Abstract: The dam site of Yangfanggou Hydropower Station is located in a narrow river valley, where slopes on both banks are as high as 500- 600m, and with numerous dangerous rock masses. There are large collapsed accumulated bodies and debris flow gullies near the dam area. Yangfanggou Project dam is a concrete double-curved arch one, with crest outlet and mid-level outlet in the dam body, cushion pool at dam toe and auxiliary weir, and the diversion system is arranged in the mountain body on the left bank. By developing dynamic design and technological innovation, the construction is progressing smoothly. Rich experiences have been obtained in the treatment of dangerous rock mass, the dynamic design of underground cavern and slope support, the optimization of arch dam shape and flood discharge energy dissipation, and the treatment of slope collapse.
Key words: layout of hydro-complex, dangerous rock mass treatment, dynamic design of underground cavern and slope support, optimization of arch dam, Yangfanggou Hydropower Station
