对某中型水库清淤工程建设方案的研究

Research on the Construction Scheme of a Medium-sized Reservoir Dredging Project

甘肃省某中型水库在多年的运行过程中,至2021年水库已经淤积了985.9×104m3,库容损失了32%左右,入库沙量近50×104t,严重的制约了该水库工程经济效益的发挥。文章在分析清淤工程建设必要性基础上,从工程选址、淤积处理方式、工程总布置、总体施工方案等方面进行研究,提出了水库清淤的工程方案,为水库清淤工程设计施工提供技术参考和实践经验。

During the operation of a medium-sized reservoir in Gansu Province for many years,by 2021,the reservoir had accumulated 985.9×10^(4)m^(3) of sediment,resulting in a loss of about 32%of storage capacity and a sediment inflow of nearly 50×10^(4)t,severely restricting the economic benefits of the reservoir project.On the basis of analyzing the necessity of dredging engineering construction,this paper explores from the aspects of project site selection,sedimentation treatment methods,overall project layout,and overall construction plan.It proposes an engineering plan for reservoir dredging,providing technical and practical experience for the design and construction of reservoir dredging projects.
