摘要
首先对以往波浪作用下透空式平板上托力研究进行了回顾,在此基础上,通过系列模型试验,对波浪上托力产生的机理进行了详细的分析和论述,认为透空式平板下波浪上托力主要由一个迅速上升的冲击压强和一个缓慢变化的压强构成,其中冲击压强通常远大于缓变压强,起主导作用,影响其大小的最直接因素为几何因素(即波浪冲击角)、动力因素(包括波高、波速等)和空气垫层因素,由此通过对各影响因素的分析,得到最大冲击压强计算公式,大量试验资料表明,该公式与实验值有着较好的一致性。
In this paper, an experimental study on the uplift pressure of waves on a horizontal plate over a flat bottom is conducted by use of a series of model tests. A detailed analysis is made on the formation mechanism of the uplift pressure of waves. It is thought that the impact pressure intensity is mainly affected by the geometrical factor (tangential angle of waves), dynamic factor (wave height, wave velocity, etc.) and air cushion factor. Based on the test results, effects of some important factors are analyzed, and then an equation for calculation of the maximum uplift impact pressure intensity of waves on a plate is presented. Lots of test data show that the results of present equation are in good agreement with the test results.
