摘　　要：波浪与建筑物相互作用的影响较为复杂,除与建筑物的结构型式、水深和常见的波浪要素等因素有关外,还与波浪入射的方向有关。采用整体物理模型试验手段,选用规则波在斜向波作用下对透空堤透浪特性的影响因素进行初步研究。分析不同波向角和波要素条件下,相对入射波高、相对挡板入水深度、相对波长、波向角等无量纲因素对桩基挡板式透空堤透浪系数的影响,推导在添加波向角影响因子的斜向波作用条件下透浪系数的半经验半理论计算公式,使透空堤的研究成果更贴近工程实际,对于指导透空堤的结构设计和优化有一定意义。通过使用透水性消浪构筑物来恢复沉积物平衡,稳定海岸线,减少侵蚀风险。The influence of the interaction between waves and buildings is complicated.In addition to factors such as the structure of the building,water depth and common wave elements,it is also related to the direction of wave incidence.Using the overall physical model test method,a regular wave was selected under the action of oblique waves to conduct preliminary research on the influencing factors of the wave penetration characteristics of the permeable dike.The influence of dimensionless factors such as relative incident wave height,relative baffle entry depth,relative wavelength,wave direction angle,etc.on the wave transmission coefficient of pile foundation baffle permeable dike under different wave direction angles and wave elements was analyzed.The semi-empirical and semi-theoretical calculation formula of the wave penetration coefficient under the action of the diagonal wave of the diagonal influence factor makes the research results of the permeable dike closer to the actual project,and has certain significance for guiding the structural design and optimization of the permeable dike.Permeable wave-eliminating structures is used to restore sediment balance,stabilize coastlines and reduce erosion risks.
