摘要
通过二维不规则波波压力试验,对不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地研究。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,提出了不规则波作用下开孔沉箱三个滑移稳定危险时刻的波浪力计算方法。将本文推荐方法的计算结果与试验结果比较可见,两者符合较好,推荐方法大多情况下能够给出较为安全的结果,能为实际工程提供有应用价值的结果。
Based on 2D experiments of irregular waves acting on perforated caisson , systematical study is done on wave forces acting on perforated caisson.In consideration of the maximum total horizontal wave force and the maximum total vertical wave force are not simultaneously appeared due to the effect of wave absorbing chamber in the perforated caisson, the phase difference between the maximum horizontal wave forces and the maximum vertical wave forces is regressed from the experimental data. The methods for the calculation of simultaneous horizontal and vertical wave forces on perforated caisson in three cases for sliding stability analysis are described.
