摘要
叶尔羌河在卡群站以下修建各级引水枢纽后,其工程引水时大多采取了排沙措施,使得在引水的同时,将大量泥沙排于河道,使下泄水中的挟沙量相对增大,改变了河流天然形态,受人为因素影响,大量泥沙在闸前、闸后河段淤积。艾里克他木水利枢纽地处平原灌区,地势平缓,河段为典型的游荡性河槽,主槽不稳定,河床冲淤变化情况复杂,治理难度逐年加大。
After the construction of water diversion projects at various levels at the downstream of Kaqun Stations, de-silting measures are taken while water is diverted to de-silt sediment into the river, leading to the increase of sediment in the discharged water and changing the river natural form. Influenced by man-made factors a large amount of sediments deposit in front of gate and back of gate. Ailiketamu Hydro-junction is located a plain irrigation area, with a flat topography, mobile water channel, unstable main stream and complicated riverbed scouring and silting changes, posing a big management challenge year by year.
