海滩泥沙促淤防冲技术研究进展与展望

Advances and Prospects in Study on Siltation Promotion and Erosion Control Techniques for Beach Sediments

将海滩泥沙的促淤防冲技术方法按结构物的型式分为3大类:实体不透水型、生态型和其他新颖结构型式。分别阐述了这3类型式的作用机理以及应用中应考虑的主要因素;结合这3类技术在海岸工程中的应用实例及其效果分析,分别总结其优缺点。介绍了促淤防冲技术的最新发展动态,指出安全、经济、高效和环保是其发展趋势,建议采用施工易、造价低和阻水小的结构和轻质材料。

In this paper, the siltation promotion and erosion control techniques for beach sediments are divided into three types, impermeable solid type, ecological type and new structure type. The working mechanisms of the three types of technique and the main factors needing attention in their applications are respectively expounded. The advantages and disadvantages of these techniques are summarized by using the cases of their applications to coastal engineerings. The recent developments in the siltation promotion and erosion control techniques are introduced, and it is pointed out that the developing trends of these techniques are safe, economical, efficient and environment-friendly. Therefore, the structures characterized by light weight, low cost, small resistance to flow conveyance and being easy to construct are highly, recommended.
