【摘要】：为解决多沙河流上的湖泊型水库的泥沙淤积问题,提出利用水库地形条件,通过在库区设置拦沙墙形成"库中库"的排沙蓄水模式,并以德日苏宝冷水库为例,对设置拦沙墙的防沙及冲沙效果进行了物理模型试验和水流泥沙数值模拟研究。结果表明,在多沙水库中采用"库中库"模式既可防止副库区淤积,又能增强主库区的拉沙效果,是一种解决湖泊型水库库区泥沙淤积的有效工程措施。
[Abstract]:In order to solve the problem of sediment deposition in lake reservoirs on sandy rivers, this paper puts forward a model of sediment discharge and water storage by setting up sand retaining walls in the reservoir area by using reservoir topographic conditions, and taking the Dejisubaoleng Reservoir as an example, The physical model test and numerical simulation of sediment flow and sediment were carried out on the sand control and scouring effect of sand retaining wall. The results show that the model of "middle reservoir in reservoir" can not only prevent deposition in secondary reservoir area, but also enhance the effect of sand pulling in main reservoir area. It is an effective engineering measure to solve sediment deposition in lake type reservoir area.
