摘要
以粤东后江湾出海航道两侧拟建防波堤为工程背景,应用海岸动力学原理,建立了海岸演变的一线模型。模型考虑波浪的绕射,考虑了沿岸波高不等所引起的沿岸输沙。通过实际岸线与模拟岸线的对比分析,论证了该模型是成功的。应用该模型对粤东后江湾修筑拦沙堤后的岸线演变进行预报,其结果表明,在海湾两岬角处海滩侵蚀,湾顶堤头处海滩淤积。东北岸段拦沙堤处海滩的淤积速率为5～6m/a,西南岸段为4～5m/a。
A one-line model has been established in the paper. The model has proven successful in predicting shoreline evolution by comparing the factual shoreline and the simulated shoreline. The model is applied to predict the shoreline evolution of Houjiang Bay after the breakwater has been built. The result shows that erosion will happen in the headland and sedimentations will happen in the middle part where the breakwater will be built. The speed of sedimentation is 5-6 m/a in the northeast part and 4-5 m in the southwest part.
