摘要
针对密排桩基防波堤波浪力计算的问题,基于某密排桩基防波堤工程,进行密排桩基防波堤波浪力的物理模型试验研究.结果表明:密排桩基防波堤波浪力计算可采用直墙式建筑物波浪力理论公式,OCDI公式结果与试验值较接近;波浪力沿堤身轴线呈现堤身大、堤头小的趋势;斜向浪对密排桩基防波堤波浪力有一定影响,可采用Goda 公式折减系数进行近似评估.
Abstract
To calculate the wave loads of closely spaced pile breakwater structure,we carry out the physical model test to do research on the wave load of closely spaced pile breakwater based on a breakwater project.The results show that the theoretical formula of wave load for vertical-walled structure can be calculated for the closely spaced pile breakwater structure,and the results of the OCDI formula is similar to the test results.The wave load along the axis of the closed-pile structure presents a trend of larger body and smaller head.Oblique waves have a certain influence on the wave load on the closely spaced pile breakwater structure,and the reduction coefficient of the OCDI formula can be used for approximate evaluation.
