莺歌咀附近岸段的岸线演变模拟

对某码头不同布置方案的适宜性进行论证、比选,提出推荐方案。从泥沙冲淤角度以及工程对岸线的影响出发,运用岬间海湾平面平衡形态经验模型,模拟出码头施建三个方案后的海岸的平衡岸线;并用一线模型对岸线的演变进行预测。利用经验模型和数值模拟相结合的方法,得到工程后岸线的演变情况。结果表明三个方案导堤两侧的海岸均为淤积,并且方案一占优,从而为工程设计方案的比选提供了一定的科学依据。

Shoreline Evolution Simulation about the beach near the Yingge Tsui

The suitability of different layout schemes of a pier is demonstrated and the recommended plan is proposed. From the perspective of sediment deposition and its impact on the shoreline, the shorelines for three plans are simulated by employing the static equilibrium head-bay coast model .Additionally,the coastline evolution is also predicted with one-line model. Based on the combination of numerical simulation and empirical model, the evolution of the shoreline after the projects are constructed is obtained. The results indicate that both sides of the dike are silting for all the three plans,and the first plan is better than the other two. This paper provides a scientific basis for the comparison of scientific basis for the comparison of different design schemes of project.
