摘　　要：黑河水库是解决西安市城市供水、农田灌溉及水力发电的大型水利水电工程。其左岸的单薄分水岭既构成大坝坝肩岩体 ,蓄水后又成为一天然坝体。分水岭内切岭断层发育 ,岩体破碎 ,蓄水后可能产生渗漏 ,渗流可能会引起分水岭东侧坡体稳定及断层渗透破坏等问题 。Heihe reservoir is a huge hydroelectric project to solve the water supply for Xi′an city,farmaland water supply and hydroelectric power generation.The thin mountain ridge on the reservoir left could be used as part of the dam.But,faults in the ridge are strongly developed and result in rock mass broken.After full of the water,reservoir leakage may occur.Especially,the thin mountain ridge will lose its stability and faults will be further broken under the seepage.In this paper,every prossibility of the problems mentioned above is analyzed.
