中文摘要：

通过二维规则波波压力实验，对规则波作用下无顶板开孔沉箱所受到的波浪力进行了系统研究。针对开孔沉箱由于具有特殊的消浪室结构导致其所受到的总水平与总垂直波浪力存在相位差，给出了相位差的计算公式，提出了开孔沉箱波浪力峰谷值时刻同步波浪力的计算方法，为开孔沉箱的工程应用提供了有价值的结果。

英文摘要：

Through 2-D experiments in the wave flume, systematic study was carried out on wave forces acting on perforated caisson. Considering the phase difference between the total horizontal wave force and total vertical wave force acting on perforated caisson due to the special structure of wave dissipating chamber, this paper describes the phase relation of the wave forces, and sets forth the methods for calculating the simultaneous wave forces on perforated caisson in three cases for sliding stability analysis, which provides useful data for engineering application of perforated caisson.
