船闸引航道推移波分析

Analysis of translatory waves in ship lock approach

船闸灌泄水过程中,在引航道内产生非恒定流,生成推移波,从而引起水面波动和流速、流态变化,不仅会影响船舶安全过闸,也可能对船闸自身运行和安全造成不利影响。针对这一问题,分析了推移波产生机理和传播特性,给出了推移波估算的简易方法,介绍了国外关于推移波的相关规定和降低影响的措施。

In the filling or emptying process,due to irregular flow that might result in translatory wave,thesurface fluctuation,flow velocity and flow pattern might change,and the lock operation and safety might be affected.In this paper,the generation mechanism and propagation characteristics of translatory waves are analyzed,and theestimation methods of translatory wave are given.Relevant regulations and measures to reduce the impact fortranslatory wave are introduced.
