| 摘 要： | 桥墩建在航道中,干扰了天然的水流运动,在其周围形成紊流区,影响到建桥水域的河床演变和航道稳定.桥墩附近存在不安全的航行区域,导致船舶碰撞桥墩事件时有发生.开展桥墩紊流宽度的研究对水运、桥梁建设等方面有着重大的现实意义.回顾了国内外对桥墩紊流宽度的研究进展,从桥墩周围水流紊动特性研究、紊流宽度影响参数分析及公式计算、桥墩紊流对通航净宽的影响3个方面概述了该领域的研究现状与发展趋势,分析了存在的问题并提出了需要进一步研究的方向.

| Abstract: | When a pier is built in the waterway,the natural flow is disturbed,and turbulence around the pier is formed,which affects river bed evolution and channel stabilization of the water area near the bridge.Ship collisions with piers take place every year because turbulence around the pier affects navigation safety.It is of practical significance to study the pier turbulence width during water transportation and bridge construction.More work is needed on this topic in China.Based on the published literatures abo... |
