人工水下沙坝研究进展

A Review of Studies on Submerged Berms

从波浪作用下人工水下沙坝的迁移演变规律和人工水下沙坝对波浪的消减效应2个方面综述了人工水下沙坝与波浪相互作用相关的最新研究进展;介绍了人工水下沙坝物理试验研究的经典案例,包括案例的研究背景、比尺设计原则和主要结论;论述了适用于人工水下沙坝中长期演变模拟的“基于过程的剖面演变模型”的发展历程和核心思想;结合现有研究成果,从构筑长度、布设位置和工程寿命设计方面给出了人工水下沙坝工程应用上的建议;讨论了现有研究成果和研究方法的局限性,给出了未来的研究展望。

An overview of the latest research progress on the interaction between submerged berms and waves is given from two aspects, the evolution of submerged berms under the effects of waves and the wave dissipation effect of submerged berms. Classic experimental studies of the interaction between submerged berms and waves are reviewed,and their research background,scaling criteria, and main conclusions are introduced. The development process and core idea of“process-based profile evolution model”, which is suitable for the simulation of medium-and long-term evolution of submerged berms,are expounded. Suggestions on the engineering application of submerged berms are given from the aspects of longshore length, nourishment location, and lifetime design. The limitations of conclusions and methodologies of existing studies are discussed,and future research prospects are proposed.
