越浪对斜坡式护岸后方危险品管廊的影响

Impact of wave overtopping on dangerous cargo pipe gallery behind sloping revetment

随着极端灾害天气的增多,建港条件恶化,已建斜坡式护岸不能对后续建设的危险品管廊形成安全掩护。论证掩护危险品管廊斜坡式护岸的防潮、防浪和越浪量标准,采用规范公式计算掩护危险品管廊的斜坡式护岸堤顶高程,通过波浪断面物理模型试验研究越浪量、越浪水面线、越浪落水点位置和波浪力,分析越浪对斜坡式护岸后方危险品管廊的影响,提出堤顶高程无法满足越浪量控制标准的管廊建设方案。

With the increase of the extreme weather,port construction conditions become harsh,and the sloping revetment already built cannot form a safe shelter for the dangerous cargo pipe gallery built consequently.This paper demonstrates the moisture-resistance,wave protection and overtopping standards for the sloping revetment,calculates the crest elevation of the sloping revetment using the standard formula,studies the overtopping volume,the wave overtopping surface curve,the location of wave overtopping and the wave force based on the physical model test of the cross-section,analyzes the influence of overtopping on the dangerous cargo pipe gallery behind the sloping revetment,and proposes the construction options of the dangerous cargo pipe gallery,in which the crest elevation of sloping revetment cannot meet the control standard of the wave overtopping.
