| 中文摘要: |
| 通过物理模型试验，研究了不规则波作用下滨海斜坡复式护岸断面波浪最大爬坡距离和爬坡流厚度，探讨了最大爬坡距离和爬坡流厚度的影响因素及其影响规律，发现两者都随着护岸前沿平均越浪量的增大而增大，同时随着距护岸前沿距离的增大，爬坡流厚度减小．在此基础上建立了爬坡距离和爬坡流厚度与各影响因素的关系，并参考相关研究成果讨论了比尺效应对试验结果的影响，当坡度小于1∶8时，比尺效应的影响在5%以内．研究结果可为工程设计和相应的数值计算提供参考． |
| 英文摘要: |
| Through physical model test, the maximum wave ascent and the thickness of wave run-up flow on coastal compound slope revetment are studied with irregular waves, and the affecting factors and their influence rules are discussed. It is found that both of them increase with the increasing of mean wave overtopping discharge at the front of revetment, meanwhile the thickness of wave run-up flow decreases with the increasing of distance from the front of revetment. On this basis, the relationship between wave ascent and the thickness of wave run-up flow and their affecting factors is built, and the scale effects are studied further. When the slope is less than 1∶8, the influence of scale effects is within 5%. The experimental results can be taken as reference for real engineering design and numerical calculation. |
