摘　　要：在印度洋、大西洋沿岸,海岸工程设计波浪周期多在14 s以上,具有显著的中长周期波特征。通过以往工程项目的试验结果发现中长周期波下,规范计算的斜坡堤胸墙波浪力明显小于试验结果。因此,通过系列物理模型试验研究了中长周期波下的斜坡堤胸墙波浪力。分析斜坡坡度、肩台宽度和波浪条件对胸墙波浪力的影响。通过将试验结果与我国现有规范中的经验公式计算所得结果进行对比,发现规范更适用于胸墙底淹没的情况,而对于肩台出水情况,规范计算结果小于试验结果。由此提出了一种新的波浪力计算方法,计算准确度得到明显提高。On the coasts of the Indian Ocean and Atlantic Ocean,the design wave period of coastal engineering is more than 14 s,which has obvious medium-long period characteristics.Through the experimental study of the practial engineering,it is found that the wave force calculated by the Code of China Design(CCD)is obviously smaller than the experimental result under the medium-long period waves.Therefore,a series of physical model tests have been carried out to study the wave force on crown wall under medium-long period waves.The effects of slope,berm width and wave period on wave force are analyzed.By comparing experimental results with the empirical formula calculation results of CCD,it is found that CCD is more suitable for the bottom of the bottom of submerged crown wall.For the conditions of the bottom of the non-submerged crown wall,the results of the CCD are smaller than the test results.Therefore,a new method is proposed to evaluate the horizontal wave force on crown wall.The results of the new method are more accurate than the CCD.
