摘　　要：雅鲁藏布江中游某水电站在库区6.7km范围内发育有11条泥石流沟,泥石流发生频率较低。本文主要通过对库区各石流沟的危险性、堵江可能性及对水电站工程设施的影响三个方面进行分析讨论,进而综合分析库区泥石流的工程影响。其中3条沟距离坝址较近,危险性较大,会对坝址区水工建筑及施工安全造成一定影响,库区泥石流不会造成严重的堵江问题。水库蓄水后,库区泥石流堆积区急剧后退,对水库正常运营影响较小。There are 11 mud-rock flow channels in the reservoir of a hydropower station in the middle of the Yarlung Zangbo River. Frequency of the occurrence of debris flow is low. This paper comprehensively analyzes the effect of mud-rock flow in the dam site on project mainly through analyzing the fatalness of each mud-rock flow in the reservoir, the possibility of blocking up and the impact on hydropower station job projection. Among these channels, three channels are near the dam site and have great influence on waterwork in the dam site and construction safety. The results indicate the debris flow activities in the study area will not result in blocking of the main channel that possibly brings about flood in the down stream of the river.
