| 摘 要： | 为探求斜坡堤典型胸墙迎浪面所受波浪力大小的影响因素，设计前仰式、深弧式、后仰式和直立式四种结构型式胸墙进行相关的物理模型试验。通过在典型胸墙迎浪面间隔布置压力测点获取所受波浪压力，并将其进行积分求和得到胸墙所受波浪力，进而讨论相对波高(H/d)、相对波长(L/d)、斜坡坡度和胸墙结构型式对波浪力的影响。试验结果表明：相对波高与相对波长对胸墙所受波浪力影响显著。波浪力随着相对波高的增大而增大，随着相对波长的增大呈现先增大—后减小—再增大的变化趋势。波浪力随着斜坡坡度的增大而减小。斜坡堤弧形胸墙所受波浪力明显大于直立式胸墙所受波浪力；在斜坡堤弧形胸墙中，前仰式胸墙受力较其余两种型式胸墙受力小。研究结果将加深波浪对斜坡堤胸墙作用力的理解，为后续工程设计提供理论指导。

| Abstract: | To pursue the influencing factors of wave load on the typical crest wall of sloping breakwater, the physical model experiment is carried out about the four crest walls including lean-front type, deep-arc type, lean-back type and vertical type. The wave load is obtained from the integral of the wave pressures on the different locations of the crest walls. Then, this paper analyzes the relationship between the wave load and the relative wave height(H/d), relative wave length(L/d), slope and the type of the crest wall. The research results show that, the relative wave height and relative wave length have significant effects on the wave load. The wave load increases with the increase of the relative wave height and it presents the variation trend of firstly increase - then decrease - finally increase with the increase of the relative wave length. While the wave loads decrease with the increase of the slope. For the same wave conditions, the wave load on the arc crest walls of sloping breakwater is bigger than that on the vertical crest wall. And the wave load on lean-front crest wall is smaller than that on the deep-arc and lean-back crest wall among the arc crest walls. The research results will deepen the knowledge about the wave load on the crest wall of sloping breakwater and provide the theoretical direction for the subsequent engineering design. |
