摘要
拟建中型水库建成后来沙量较大,水库运行过程中泥沙淤积问题严峻,同时泥沙的淤积将影响后期水库的回水距离。采用《土壤侵蚀现状图》来估算泥沙淤积高程及泥沙淤积量,并通过水面线计算程序MIKE 11水动力模块和泥沙模块进行水库回水分析,泥沙淤积高程和淤积量呈逐年增加趋势,水库回水变化符合一般回水规律,可为相似工程泥沙淤积与回水分析提供技术参考依据。
After the proposed medium-sized reservoir was completed, the amount of sediment was relatively large,and the problem of sedimentation during the operation of the reservoir was severe. At the same time, the siltation of sediment will affect the backwater distance of the reservoir in the later stage. The "Soil Erosion Status Map" is used to estimate the sedimentation elevation and the amount of sedimentation. And through the water surface line calculation program MIKE 11hydrodynamic module and sediment module to analyze the reservoir backwater. The siltation elevation and siltation volume are increasing year by year, and the backwater changes of the reservoir are in line with the general backwater law. The results can provide a technical reference for the analysis of sedimentation and backwater in similar projects.
