| 摘 要： | 针对在淤泥质海岸建筑防波堤引起的港内泥沙淤积问题,以坎门渔港三期防波堤工程为例,采用潮流数学模型和泥沙冲淤半理论半经验公式,研究不同的防波堤布置对潮流、泥沙淤积的影响。结果表明,从港内泥沙淤积的角度看,在淤泥质海岸布置防波堤时宜尽可能保持工程前的流路。

| Abstract: | For silt accumulation inside harbors caused by construction of breakwaters in silt coasts,the 3rd stage breakwater project of the Kanmen Fishery Harbor was taken as a case in this paper,and the impact of different breakwater layouts on tidal current and silt accumulation was studied by means of a numerical model of tidal current and a semi-theoretical and semi-empirical formula of erosion and accumulation.The results show that from the point of view of the silt accumulation inside harbors,current paths after the construction of breakwaters should be close to those before the construction of breakwaters as possible while breakwaters in silt coasts are designed. |
