Study on wave overtopping of sloping breakwater with accropode armor blocks under medium-long period waves
摘要
Abstract
As a preconstruction project for port hydraulic structures,sloping breakwater are crucial for the safety and stability of port engineering construction.Wave overtopping is a controlling indicator for measuring the safety and effectiveness of sloping embankments.Accropode armor blocks are widely used in international sloping breakwater engineering projects,and international engineering faces harsh hydrological conditions with long cycles and high waves.However,the current regulations lack a calculation criterion for the wave overtopping of the sloping breakwater with accropode armor blocks under such conditions.Therefore,through a series of physical model tests,the effects of effective wave height,relative water depth,and spectral peak period on the overtopping of sloping breakwaters under medium-long period waves were analyzed.By comparing and analyzing the experimental results with the results obtained from empirical formulas in current domestic and foreign standards,it is found that the applicability of the existing formulas is limited.Based on experimental data,the formula for slope roughness coefficient has been optimized,and it is recommended to use the optimized average value approach of EurOtop for calculation.The research results can provide reference for engineering applications in medium and long period marine areas.关键词
