摘要:
丹江口水库是由汉江库区和丹江库区组成的并联水库。根据多年平均入库水沙资料，分析了水库的水沙特性和淤积变化。结果表明，丹江口水库入库水沙地区分布极不均匀，汉江库区来水量和来沙量占绝大多数。入库水沙年内分布也极不均匀，来水来沙量均集中于汛期。水库干流库区淤积量占全库的85%左右，支流库区淤积量在15%左右。在干流库区中，汉江库区淤积量占全库的70%左右，淤积主要发生在汉江库区。汉江库区泥沙颗粒组成常年回水区以泥土为主，占81.9%～100%；变动回水区以泥沙为主，占46.8%～98%。汉江干流库区纵向淤积特点是常年回水区淤积多，变动回水区少；从库容变化上来看，中间库段库容损失大；两头库段库容损失小。横断面淤积特点主要分布在两岸边滩。最后，对丹江口水库泥沙淤积变化进行了预测分析。
Abstract:
Danjiangkou reservoir make up of Hanjiang river reservoir area and Danjiang river reservoir area which is parallel connection reservoir.According to incoming runoff and sediment process data of average per year,characteristics of incoming runoff and sediment process and sediment accumulation of reservoir was analyzed.Results showed that incoming runoff and sediment process of reservoir area distributing and annual distribution aren’t very much uniform,Hanjiang river reservoir area and flood season is possessed of absolute majority.Sediment accumulation of main stream reservoir area is approximately 85%,branch stream is approximately 15%.Sediment accumulation of Hanjiang river reservoir in the main stream reservoir area is approximately 70% of the whole reservoir,its sediment accumulation is most.Sediment grain mostly structure of perennial backwater region is clay,which is possessed of 81.9%～100%.Variable backwater region is most of sand,which is possessed of 46.8%～98%.Longitudinal section sediment accumulation in the Hanjiang river main stream reservoir is perennial backwater region more and variable backwater region less,reservoir capacity loss is middle more and both ends less.Transverse sediment accumulation is mostly which lies in the slope bottomland.In the end,sediment accumulation change of reservoir was predicted.
