不同形式护面块对斜坡式防波堤波浪爬高的影响

我国现行的几种规范关于波浪爬高的计算存在着诸多不足,特别是在长波条件下,提供的经验公式的适用条件比较局限,甚至未考虑长波因素,故其计算值与实际结果偏差很大,造成安全隐患。通过系列断面物理模型试验,研究斜坡堤上不同护面形式对不规则波浪爬高的影响规律,提出相关系数和经验计算公式,为水面开阔地区迎水面护面设计提供理论参考。

Wave run-up influenced by protective facings of sloping breakwater

Some calculation methods of wave run-up stipulated in Chinese codes have some defects,especially under the long wave condition.The formulas of relatively limited applicability even do not take long wave into account.So there is a huge deviation between the calculated value and the actual result,which may cause some potential danger.This paper mainly studies the influences of different types of protective facings of sloping breakwater on the irregular wave run-up through a series of sectional physical model tests and proposes the correlation coefficient and empirical formula to provide theory reference for the design of protective facing on the river side slope which is on open water areas.
