静态平衡岬湾海岸理论及其在黄、渤海海岸的应用

岬湾海岸是一种稳定的海岸存在形式,在天然海岸中岬湾地貌占51%。岬湾海岸研究是研究砂质海岸稳定性及演变的重要内容。岬湾海岸理论在海岸稳定性、海岸工程预测以及海岸综合治理方面有其重要的工程价值。文中详细讨论了岬湾理论中最具工程意义的抛物线型岬湾海岸线及基于静态平衡岬湾海岸理论开发的可视化应用软件MEPBay在海岸工程中的应用,并验证了该理论对黄、渤海海岸的适用性。MEPBay软件不仅有助于理解海岸形态过程,也是海岸工程师在岸线保护及海岸管理实践中的有力辅助工具。

Static Equilibrium Headland-bay Coast Theory and Its Application to Coasts of the Yellow and Bohai Seas

The headland-bay coast is a kind of stable coast,the study on headland-bay coast is of importance to the study on sandy coast stability and evolution,and the headland-bay coast theory is of great value to the coast stability,coastal engineering prediction and comprehensive regulation of coast.In this paper,the parabolic headland-bay coast shape model,the software MEPBay developed on the basis of static equilibrium headland-bay coast theory and its application to the coastal engineering are discussed,and the applicability of the static equilibrium theory to coasts of the Yellow and Bohai Seas is also validated.Software MEPBay not only helps understand the coast morphological process,but also provides a powerful tool to the engineers in practising the shoreline protection and coastal management.
