摘　　要：传统直立和斜坡式海塘挡墙结构在强降雨或极端风暴潮条件下难以有效阻止潮水快速爬升,对岸线建筑物及人群产生一定安全隐患。该文通过数值模拟设置不同水位高度,研究不同冲击水流流速对新型反弧式海塘挡墙结构越浪效果的影响,以评价新型海塘挡墙的越浪效果。研究结果表明,新型反弧式海塘挡墙结构在不同水流流速下的越浪效果均优于传统海塘挡墙结构,新型反弧式海塘结构具有明显导流、减能的作用。Under the condition of heavy rainfall or extreme storm tide,the traditional vertical and sloping seawall structure fail to effectively prevent the tide from climbing rapidly,resulting in certain safety risks to shoreline buildings and people.In this paper,different water level heights are set by numerical simulation to study the influence of different impact flow velocity on the wave-crossing effect of the new anti-arc seawall structure,in order to evaluate the wave-crossing effect of the new seawall.The results show that the wave surging effect of the new anti-arc seawall structure is better than that of the traditional seawall structure under different flow velocity,and the new anti-arc seawall structure has obvious effect of diversion and energy reduction.
