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.
