摘　　要：新疆地区水库具有多泥沙特点,是造成水库库区水位抬高、库容降低的主要原因。文章以新疆克孜尔水库建设为工程实例,在水流运动、悬沙淤积相似条件基础上,计算出水库坝前及泄水底孔内泥沙淤积形态断面模型比尺,通过建立的试验模型对水库坝前及泄水底孔内泥沙淤积形态断面进行分析,对指导水库汛期排沙及大坝检修有重要作用。Reservoirs in Xinjiang are characterized by heavy sediment,which is the main reason for the elevation of water level and reduction of reservoir capacity.The construction of Xinjiang Kizil Reservoir is regarded as the engineering example in the paper.The sediment accumulation pattern sectional model scale in front of the reservoir dam and in the drainage bottom hole are calculated based on water flow movement and suspended sediment accumulation similar conditions.The sediment accumulation pattern section in front of reservoir dam and in drainage bottom holes are analyzed through the established test model.The paper plays an important role to guidance of reservoir sand discharge during flooded season and dam overhaul.
