摘要
通过对具有代表性的某宽坦式急流河道闸坝工程进行水工模型试验,根据闸后水流特点,总结了该类工程消力池设计需要注意的重点.试验研究表明:为了确保推移质能够顺利地通过消力池随水流带往下游,尽量减少池内淤积,同时消力池出池水面与池后下游河道水面较好的衔接,宽坦式急流河道闸坝工程闸后消力池内水流消能不能太充分,消力池深度和长度不能太深和太长,使出池水流具有一定的能量,有利于排沙和与下游河道水面的自然衔接.试验成果可为具有相同工程特点的消力池优化提供借鉴.
Experiments were conducted on the representative dams engineering on the wide and flat rapid flow river. According to the flow characteristics after the sluice gat, the principle of stilling basin for the engineering design was summarized. Experimental research showed that in order to ensure that bed load can be carried smoothly through the stilling basin with flow to downstream, reducing aggregation of the pool and good connection of the water surface after going out of the stilling basin with that of the downstream, the stilling basin for dams engineering on the wide and flat rapid flow river shouldn＇t have excellent energy dissipation effect. The depth and length of the stilling basin can＇t be too deep and too long, so that the flow energy could be kept at a certain level in favor of sediment flushing and natural cohesion with the downstream. Test results can provide reference for stilling basin optimization with the same engineering characteristics.
