海底沙波是一种广泛分布于世界大洋和沿海海域的海底地貌形态.海底沙波是海洋灾害地质学和海洋沉积动力学研究的重要对象,也是海洋工程建设和海岸保护管理考虑的潜在目标.海底沙波的形成和演化经历着极其复杂的过程,是海水动力、沉积物供给量、粒径、黏聚力作用、水深、地形特征和海平面波动等因素综合作用的结果.基于大量文献的综述和研究,本文从外部形态和内部结构特征、形成和发育的影响因素、运移等3方面论述了海底沙波的研究进展,同时对未来海底沙波研究的发展方向作了几点展望,即:多学科理论、多技术手段、定量化研究和国际化合作.
Submarine sand wave is a kind of submarine topography which is widely distributed in the world’s oceans and coastal waters.Sea sand wave is an important object of marine disaster geology and marine sediment dynamics research and also a potential target for marine engineering construction and coastal protection and management considerations. The formation and evolution of the submarine sandwaves undergo an extremely complicated process, which is the result of the combined action of seawater power, sediment supply, particle size, cohesive force, water depth, topographic features and sea level fluctuation.Based on a large number of documents In this paper, the research progress of submarine sandwaves is discussed from the perspectives of external shape and internal structure, influencing factors of formation and development, migration and so on. At the same time, some prospects of the future research of submarine sandwaves are prospected, Namely: multidisciplinary theory, multi-technical means, quantitative research and international cooperation.
