摘要
喀拉玉尔滚河五团龙口引水枢纽工程经过多年运行已不能发挥作用,急需进行除险加固。由于新疆地区特殊的水沙特点使得水利枢纽在运行过程中由于泥沙堆积无法下泄到河道中,严重影响枢纽工程发挥作用,因此在除险加固设计中,急需通过水工模型试验进行设计方案合理性的验证,采用正态1∶40模型比尺进行模型的构建,通过冲沙闸的不同布置形式观测冲沙闸的拉沙效果,选取冲沙闸的最优布置方案,为设计提供科学依据。
Kala Yuergun River Wutuan Longkou water diversion hub project has been unable to play its role after operation for many years. It is urgent to remove risks and reinforce the project. The water diversion hub project can not discharge water into the river due to sediment deposition during operation according to special water sand characteristics in Xinjiang,thereby seriously influencing the role of the hub project. It is urgent to verify the design plan rationality through hydraulic model tests during risk removal and reinforcement design. Normal 1 ∶ 40 model scale is adopted to build the model. The sand drawing effect of the scouring sluice is observed according to different layouts of the scouring sluice. The optimal layout of the scouring sluice is selected,thereby providing scientific basis for design.
