【摘要】：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。
[Abstract]:The suitability of different layout schemes of a wharf is demonstrated, compared, and recommended schemes are put forward. From the point of view of sediment scouring and siltation and the influence of engineering on shoreline, this paper uses the empirical model of equilibrium form of bay plane between headlands to simulate the balanced shoreline of coast after three schemes of wharf construction, and forecasts the evolution of shoreline by first-line model. By combining empirical model with numerical simulation, the evolution of shoreline after engineering is obtained. The results show that the coasts on both sides of the three schemes are silt, and the first scheme is dominant, which provides a scientific basis for the comparison and selection of engineering design schemes.
