摘要
为研究阿拉尔市“一河两岸”综合治理工程实施后可能带来的泥沙淤积问题,采用动床实体模型,拟定水沙条件,开展试验研究。试验结果表明:闸上游河道在经历初期的累积性淤积后,能够逐步实现动态平衡,不会产生持续累积性淤积;泥沙淤积基本都分布在闸上7.5km河段内;非汛期大水敞泄运用可使非汛期淤积比平均值降低约60%,同时汛期敞泄运用对于河道减淤、抑制累积性淤积起着关键作用。
A movable bed solid model is adopted to formulate the water and sediment conditions and carry out experimental research in order to study the possible sediment deposition problem after the implementation of‘One-River Two-Bank’comprehensive treatment project in Aral city.The experimental results show that the upstream river channel of sluice gate can realize dynamic balance gradually after the initial accumulative silting,and continuous accumulative silting is not available.The sediment deposition is basically distributed in the 7.5km reach of the gate.The average sedimentation ratio of non-flood season can be reduced by about 60%through the application of flood open discharge in the non-flood season.Meanwhile,the application of flood season open discharge plays a key role in reducing silting and inhibiting cumulative silting in river channels.
