| 摘 要： | 为研究在不同比尺模型下,透空式海洋结构中开孔沉箱内部受力与入射波浪的关系及差异,针对简化的上部开孔箱体海洋结构,选取两组不同尺寸模型进行了多组规则波物理模型试验。首先采用低通滤波方法分析了冲击力的不同组分,然后对比了两组模型内部所受冲击力的分布及波要素与箱体内部受力的关系。研究发现,波面对开口的淹没程度是影响冲击过程的主要因素;当模型尺寸发生变化时,开孔箱体内部所受波浪力与入射波要素的关系也发生了变化。

| Abstract: | In order to study the relationship between the wave pressure inside perforated caisson and the incident wave factor in different scale models, a series of regular wave model tests were performed on a simplified upper perforated caisson marine structure. Firstly, the different compenents of the impact force are analyzed by using the low-pass filter method, and then the distribution of the wave impact pressure and the relationship between the wave fator and the pressure are studied. It is found that the height of the wave surface is the main factor affecting the wave impact; and when the size of the model changes, the relationship between the wave force inside the perforated caisson and the incident wave factor also changes. |
