风暴潮期间水位变化条件下的海堤越浪量研究
Study on changes in wave overtopping volume of seawalls under variable water level conditions during storm surge events
摘要
Abstract
During storm surges,variations in water levels lead to dynamic changes in the relative freeboard of sea dike structures,necessitating improvements to the existing wave overtopping discharge formulas designed for constant water levels.To address this,this study uses FLUENT software to simulate wave overtopping processes under realistic storm surge hydrodynamic conditions,and analyzes the spectral characteristics of waves under varying water levels.Based on these analyses,the Eurotop(2018)wave overtopping formula is revised,and a new calculation formula for wave overtopping discharge is developed by introducing the concept of relative equivalent freeboard under variable water levels.This approach extends the applicability of the Eurotop(2018)formula and enhances its computational accuracy.关键词
