摘　　要：结合湖北漳河水库除险加固工程,采用数值模拟方法计算台阶式护坡的消浪效果,研究台阶式护坡的结构参数及大坝上游不同坝坡坡比对台阶式护坡消浪效果的影响。研究结果表明:同一入射波下,坡比相同时,平均波浪爬高随台阶相对高度的增加呈先减小后上升趋势;同一入射波下、相对台阶高度相同时,平均波浪爬高随上游坝坡坡比的增加呈先减小、后增加、再减小的趋势,总体呈减小趋势。计算分析结果表明,漳河水库鸡公尖大坝采用台阶式护坡可有效降低波浪爬高。Taking Zhanghe Reservoir Reinforcement project in Hubei Province as an example,numerical simulation method is used to analyze the wave dissipation effect of stepped slope protection,including the influence of structur⁃al parameters of stepped revetments and dam upstream slope ratio on wave dissipation effect of stepped slope protec⁃tion.The results show that for the same coming wave and slope ratio,the average wave run-up decreases first and then increases with the increase of the step's relative height;for the same coming wave and the step's relative height,the average wave run-up decreases first and then increases with the increase of the slope ratio,but in gener⁃al it experiences a decreasing trend.According to the calculation and analysis results,the stepped slope protection applied to the reinforcement of Jigongjian Dam of Zhanghe Reservoir was proved to be effective in reducing the wave run-up.
