摘　　要：防波堤主要用于维持港池水面平稳以便船舶安全停泊和作业。为了解防波堤对港内波高分布的影响,以便确定合理的防波堤扩建方案,以广西犀牛脚渔港防波堤改扩建工程项目为依托,通过原始资料分析、波浪数模计算和二维潮流数模计算,研究广西犀牛脚渔港三种防波堤扩建方案中渔港水域的波高分布。经过研究发现:由于拦沙堤的掩护,港内的波高有明显减小;防波堤对外海传入港区的大波波高掩护效果较好,但是450 m的防波堤掩护效果稍逊于400 m的防波堤;随着防波堤长度从350 m到450 m,防波堤的掩护效果增加并不明显。经综合比选,形成科学、经济、合理的防波堤扩建方案。Breakwaters are mainly used to maintain a stable water surface in the harbor for the safe berthing and operation of ships.Based on the Guangxi Rhinoceros Cape Fishing Port Breakwater Reconstruction and Expansion Project,the wave height distribution of the fishing port water area in three types of breakwater expansion schemes of Guangxi Rhinoceros Foot Fishing Port is analyzed through original data analysis,numerical simulation of waves,and two-dimensional tidal numerical simulation calculation.The results are as follows.Due to the protection of sand barriers,the wave height in the harbor has been significantly decreased;The breakwater provides better protection for high waves entering the port area from the open sea,but the protection effect of a 450 meters breakwater is slightly inferior to that of a 400 meters breakwater;As the length of the breakwater increases from^(3)50 to 450 meters,the shielding effect of the breakwater does not increase significantly.After comprehensive comparison and selection,a scientific,economic,and reasonable breakwater expansion plan has been formed.This conclusion can serve as a scientific basis for engineering feasibility planning and preliminary design decisions,and also provide reference for wave defense construction under similar conditions.
