木华里引水枢纽位于新疆库山河出山口附近,建成于1999年。工程投入运行使用后,出现枢纽处泥沙淤积、干渠引水含沙量逐年增加,使枢纽引水防沙功能逐渐减弱的问题,严重影响了枢纽的正常运行。从水文、气象、洪水、泥沙特性等方面探讨了问题的原因,并提出了处理对策。认为应对原设计重新评估,进行较大地规模的改动,并强调进行模型试验是非常必要的。
Muhuali water diversion hub located in Xinjiang Kushan River near the exit, built in 1999. After the project is put into operation, the sediment siltation at the junction and the diversion of water and sediment from the trunk canal have been increasing year by year, which has led to the gradual weakening of the function of water diversion and sediment control in the hub and seriously hindered the normal operation of the hub. The causes of the problems were discussed from hydrology, meteorology, floods and sediment characteristics, and some countermeasures were put forward. It is considered that the original design should be re-evaluated and the changes made on a large scale should be carried out. It is emphasized that it is necessary to carry out model tests.
