摘　　要：对新建金沟河引水枢纽工程进行水工模型造床平衡试验,通过对工程过流能力、闸前泥沙淤积平衡状态和运动规律进行模拟,优化了工程冲沙布置。试验研究证明工程总体布置基本合理,达到了引水闸进口的“门前清”,可避免河道大量粗颗粒泥沙进入引水系统带来的磨蚀和淤积问题,保持引水枢纽长期有效。根据试验结果提出了合理的枢纽调度方案。The hydraulic model bed building balance test is carried out for the newly-built Jingou River Diversion Project.The project flow capacity,sediment deposition balance state in front of the gateand movement law are simulated.The sand flushing layout of the project is optimized.The test results show that the overall layout of the project is basically reasonable,thereby achieving the“gate clearance”at the entrance of the diversion gate,avoiding the abrasion and siltation problems caused by a large amount of coarse silt entering the diversion system,and keeping the diversion hub effective for a long time.A reasonable hub scheduling scheme is proposed according to experimental results.
