摘要:
复式海堤作为重要的护岸基础设施，能够保护海岸免受潮流和波浪侵蚀。通过物理模型试验，研究不同块体护面复式海堤对波浪爬坡高度的影响，发现：1）三向孔块体护面下的爬坡高度最小，单向孔块体护面下次之，光滑护面下最大。2）对于同一块体护面，随着入射波波高或周期的增大，爬坡高度总体上逐渐增大。3）采用Wave Overtopping of Sea Defences Structures and Related Structure Assessment Manual（简称EurOtop）规范中波浪爬高经验公式推算不同块体护面的糙渗系数，评估不同块体护面消减波浪爬高的性能，三向孔块体结构在实际海岸工程中具有较好的应用价值。
Abstract:
As an important revetment infrastructure，compound seawalls can protect the coast against tide and wave attacks. Through the physical model test，the influence of the compound seawall with different block face protection on the wave climbing height is studied，and it is found that：1）The run-up height is the smallest under the three-way hole block，moderate under the one-way hole block and max under the smooth block.2）For the same protective facings，as the incident wave height or period increases，the run-up height generally increase. 3）Furthermore，the empirical formula of wave run-up in Wave overtopping of sea defences structures and related structure assessment manual （EurOtop）is used to calculate the roughness coefficient of different block protective facings，so as to evaluate the performance of different block protective facings in reducing wave run-up height，which indicating the three-way hole block structure has good application value in practical ocean engineering.
