根据波浪水槽中的模型试验结果,在本文中探讨了不规则波经直立墙反射后的一些特性以及墙前沙底的冲刷形态。为了便于比较,文中也简要地提及了规则立波对直立墙前沙底作用的主要结论。分析表明,若采用有效波高作为规则波试验中的等值波高,则由此得出的最终冲刷深度是偏于安全的。 According to the results of the model test in the wave tank, some characteristics of the irregular wave reflected by the erect wall and the erosion patterns of the sand bottom before the wall are discussed in this paper. For ease of comparison, the paper also briefly mentioned the main conclusions of the role of regular waves on the sand bottom of an upright wall. The analysis shows that if the effective wave height is used as the equivalent wave height in the regular wave test, the resulting final scour depth is biased to be safe.
