【摘要】：為解決多沙河流上的湖泊型水庫的泥沙淤積問題,提出利用水庫地形條件,通過在庫區(qū)設(shè)置攔沙墻形成"庫中庫"的排沙蓄水模式,并以德日蘇寶冷水庫為例,對設(shè)置攔沙墻的防沙及沖沙效果進(jìn)行了物理模型試驗和水流泥沙數(shù)值模擬研究。結(jié)果表明,在多沙水庫中采用"庫中庫"模式既可防止副庫區(qū)淤積,又能增強主庫區(qū)的拉沙效果,是一種解決湖泊型水庫庫區(qū)泥沙淤積的有效工程措施。
[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.
