| 摘 要： | 为了研究取水闸前泥沙淤积和闸前河床的边界条件之间的关系,对新疆某无坝引水工程进行了动床河工模型试验,研究发现在取水闸前有严重的泥沙淤积现象。从河床演变角度进行分析,闸前泥沙淤积严重主要是由于在取水口前进行人工取直,致使河床边界条件由弯曲型向顺直型改变,以及闸前流速的减小。这一研究结果对泥沙淤积问题有一定借鉴意义。

| Abstract: | In order to study the relationship between the sedimentation and the boundary conditions of riverbed upstream from the intake sluice, the mobile bed experiment has been conducted to a diversion water project without dam in Xinjiang, and it is found that the sedimentation was very serious upstream from the intake sluice. This paper analyzed its reasons form the perspective of fluvial process, and the results show that the sedimentation is mainly due to the changing of boundary conditions of riverbed from a curved one to a straight one, the reduction of flow velocity as well as the continuous supply of sediment upstream from the intake sluice.The research results have certain problems of sedimentation reference. |
