摘　　要：采用河道清淤和农田利用系统的技术方案对中小型河道进行清淤,并利用数值模拟方式对不同吸污口个数、吸污口口径与河底宽度的比值两种参数影响下河道吸污口的水力特性进行对比研究。结果表明,当吸污口口径/河底宽度=0.5、吸污口数量为1个时,河道清淤系统的工作性能最优。研究成果可为中小型河道的清淤设计和施工提供理论和经验借鉴。The river dredging and farmland utilization system is proposed to dredge small and medium-sized rivers,and the hydraulic characteristics of river sewage intakes under the influence of two parameters:the number of sewage intakes and the ratio of sewage intakes diameter to river bottom width are compared by numerical simulation.Finally,when the diameter/river bottom width of sewage intakes=0.5 and the number of sewage intakes is 1,the conclusion that the working performance of river dredging system is the best can provide theoretical and empirical reference for the desilting design and construction of small and medium-sized rivers.
