试验研究作用于准椭圆沉箱群墩上的不规则波波浪力（英文）

An experimental investigation of irregular wave forces on quasi-ellipse caisson structures is presented. Irregular waves were generated based on the Jonswap spectrum with two significant wave heights, and the spectrum peak periods range from 1.19 s to 1.81 s. Incident wave directions relative to the centre line of the multiple caissons are from 0° to 22.5°. The spacing between caissons ranges from 2 to 3 times that of the width of the caisson. The effects of these parameters on the wave forces of both the perforated and non-perforated caissons were compared and analyzed. It was found that the perforated caisson can reduce wave forces, especially in the transverse direction. Furthermore, the relative interval and incident wave direction have significant effects on the wave forces in the case of multiple caissons.     

规则波作用下准椭圆沉箱群墩波浪力试验分析

为了更好地推广准椭圆箱结构形式,了解该结构的水动力特性,采用物理模型试验研究规则波对准椭圆沉箱群墩结构的波浪力,结果表明,与正向波浪力相比,群墩效应对横向波浪力的影响更大,结构侧壁开孔对消减沉箱横向力效果明显,但对消减沉箱正向力作用有限,对大型结构准椭圆沉箱,波浪非线性的影响不容忽视,群墩代替单墩进行准椭圆沉箱的水动力研究与设计是必要的。
