摘　　要：溢流丁坝在天南维其克枢纽工程中的应用,改变了枢纽上下游的水沙特性。通过模型试验研究发现,枢纽上游左岸长溢流丁坝,可将靠左岸的主流导向右岸的引水口,稳定了长溢流丁坝末端至引水口段的主槽。同时,部分洪水可以通过丁坝泄流,使河道过流断面流量分布均匀,减轻了过分依赖一岸抗洪的问题。枢纽上游右岸丁坝的设置,将上游右岸一侧的泥沙导向远离引水口的主槽,使原进水闸闸前保持"门前清",大大减轻了入渠的泥沙量。The application of overflow groin in Tiannan Viqk Water Diversion Project is introduced here. Through the model experiment, it is found out that a long overflow groin constructed near the upstream diversion dike of left bank in the diversion works could lead the main stream near the left bank to the water diversion inlet near the fight bank and stablize the main channel from the end of overflow groin to the inlet. Meanwhile, the groin can overflow parts of water discharge, which can make the discharge distribution of the fiver cross section uniform and therefore reduce the flood prevention task which excessively depends on one bank and ensure the normal water diversion. A short overflow groin constructed near the upstream diversion dike of right bank in the diversion works would drain the sediment from the fight bank to the flood discharging sluice and solve the sediment problem efficiently.
