摘　　要：在水利工程实践和研究领域中,由于地理位置、地形特点,避免不了闸室修建在弯形河道中,弯形河道对闸室的水流特性有着重要的影响。为改变弯形河道水流对闸室的水流影响,针对建设导墙的方式对改变闸室水流条件的影响进行研究,通过试验分别观测闸室加导墙前后的水流流态、流速、水位的变化。结果表明,加导墙后流线呈稳定的曲线向下流动进入闸室,整个水面线比较平缓,流速、波动的幅度变缓,尤其是水位上升变缓慢,这对闸室过流和稳定有利。In the field of hydraulic engineering practice and research,due to the geographical location and topographical characteristics,it is inevitable to build a lock chamber in a curved channel.The influence of the gate chamber on the flow of water.This article mainly focuses on the influence of the method of constructing the guide wall on changing the conditions of the gate chamber.After adding the guide wall,the flow line flows into the lock chamber in a stable curve.The entire water surface line is relatively gentle,and the amplitude of the flow velocity and fluctuations slows down,especially when the water level rises slowly.
