中文摘要：

海底沙波普遍存在且严重危害海底工程,成为人们日益关注的热点。为了加深对海底沙波研究的认识,总结论述了海底沙波的分类与成因,重点对海底沙波迁移的预测、观测进行了分析。结果表明,对海底沙波的成因认识逐步加深、分类逐步细化,成因及迁移过程是多种水动力因素共同作用的结果,但形成及迁移的机制至今仍未有系统理论形成。由于缺乏长期观测数据,无法对海底沙波的迁移进行准确预测。今后研究的方向主要是,将理论研究与现场观测紧密结合,设计新的原位长期观测方法,完善预测模型,建立全面的资料数据库为海底基础工程预警。

英文摘要：

Submarine sandwaveis becoming the hot point in marine researchdue to the universality and harmfulness.In order to deepen the research about submarine sandwave,the classification and causes of sandwave have beensummarized,and the migrate and predict of submarine sandwave have been analyzed.The results show that the understanding of cause about sandwave gradually deepen and the classification is gradually refined,the migrate process is affected by various hydrodynamic factors.However,there isn＇t a system theory about the formation and migrate mechanism.Due to lack of long-term observation data,the migration of sandwave can＇t be predicted accurately.Based on these,it is proposed that closely integrating theoretical research and on-site observation,designing a new in situ long-term observation method,improving the forecasting model,establishing comprehensive database warning for the submarine projects,etc,are the main research directions in the future.
