摘要
对淹没式导流屏在河道治理中的作用进行了系统分析 ,认为通过淹没式导流屏在弯道段凹岸激起的次生流来消除弯道环流或在顺直河段激起的次生流 ,可促进导流屏区的淤积。因淹没式导流屏加大了导流屏区的阻力 ,减小底部流速 ,有利于导流屏区的淤积。并将系统分析与试验及已实施的工程实例进行比较 。
The effect of submerged guide vanes in the river regulation is systematically analysed. It is considered that the secondary flow caused by submerged guide vanes in the concave bank of meandering reach can eliminate the circulation flow and in straight reach may promote the sedimentation in the guide vanes region, because the submerged guide vanes can increase the flow resistance and abate the bottom velocities at the vanes area. The results of systematic analyses are in agreement with the data of experiments and engineering practice.
