毛阿提引水枢纽分水排沙试验研究

摘要

为研究毛阿提引水枢纽上下游冲淤演变状况及消能防冲效果，对毛阿提引水枢纽设计方案进行了系列动床试验，试验测定了各典型流量下枢纽上、下游河床、整治段冲淤演变情况，冲淤变化历时、冲淤范围和冲刷深度。结果表明：毛阿提引水枢纽总体布置基本合理，消能防冲效果良好。根据试验结果，给出了实际运行中的各个闸门的运行方式，供运行管理单位调度方参考。%In order to study the erosion-silting evolutions in the upstream and downstream of Mao ’ a’ ti water diversion project and its energy-dissipation and scour-prevention effects ,its design scheme has been tested through a series of allu-vial bed experiments .Meanwhile ,the siltation and erosion in its upstream and downstream reach as well as the erosion-silting changes ,scope and scouring depth are measured by the tests .The results show that the general arrangement of Mao’ a’ ti water diversion project is reasonable , and its energy-dissipation and scour-prevention effects are favorable . What’s more ,the operation modes of the gates in the practical operation are provided for the dispatching party to have reference in operation and management .
