通航隧洞内消波设施试验研究

Experimental study on wave absorber in navigable tunnels

通航隧洞是一种常见的浅水航道,属于典型的狭窄形航道,船舶在此类受限航道中航行,船舶两侧的不对称水域、船行波以及充泄水振荡波的反射叠加,将对船体产生不对称的侧向力,增加船体控制难度。针对船舶在隧洞航行时的波动问题,本文提出了一种具有立柱和横板的消波设施,采用物理模型开展船舶试验,分析设施的消能效果,经验证该设施可有效减小波动。

Navigable tunnel is a typical narrow channel with shallow water depth.When a ship sails in such channels,the asymmetric water areas on both sides of the ship,as well as the reflection superposition of the traveling wave and shockwave caused by the filling and emptying system,will cause asymmetrical lateral forces on the hull and increase the difficulty of controlling the hull.In order to solve the wave effect when the ship sails in the tunnel,this paper proposes a wave absorber with columns and transverse plates and adopts a physical model to carry out ship model tests,so as to analyze the energy-absorbing effect of the absorber.It has been verified that the absorber can reduce the wave amplitude effectively.
