摘要
本文针对中长周期波浪对斜坡堤扭王字块在位稳定性的影响开展了物理模拟试验,将高精度惯性姿态传感器与扭王字块固定,通过姿态传感器采集得到波浪作用下扭王字块的角速度时程,定量地分析波浪作用下斜坡堤扭王字块体的在位稳定性,探究了波浪周期和波高对于斜坡堤上扭王字块在位稳定性的影响。研究发现:波浪周期对扭王字块在位稳定性的影响呈非线性关系。随着波浪周期的增大,扭王字块的角速度幅值呈现出先增大、后减小、再增大的趋势。中等周期波浪作用下,静水面附近的扭王字块的变位最显著,而长周期波浪作用下,静水面上一倍波高处的扭王字块的变位最明显。
Physical simulation experiment was carried out to investigate the stability of accropodes of sloping breakwater subject the action of medium to long period waves.High-resolution inertial attitude sensors were attached to the accropodes to measure the angular velocity time-histories of the accropodes under the action of waves,quantitatively investigating the stability of sloping breakwater accropodes subject to different wave heights and periods.The results showed an non-linear relation between periodic wave and the stability of accropodes.With the increase of wave period,the angular velocity amplitude of the accropodes showed a trend of increasedecrease-increase.The accropodes near still water surface showed the most significant displacement under the action of medium period wave.However,the accropodes at one time wave height above still water level showed the most significant displacement under long period wave.
