摘　　要：海底滑坡是一种极具破坏力的海底地质灾害。其一旦发生,破坏后的块体可以高速运移至数十千米甚至上百千米远,能够对影响区域内的海洋油气生产平台、海底管道、海底电缆等海洋工程设施造成破坏性影响。本研究根据国内外海底滑坡研究领域的最新成果,简要介绍分析与海底斜坡失稳后块体运动有关的调查方法、数值模拟以及物理实验等研究的现状与进展,以期为我国今后海底滑坡地质灾害评价与防治研究提供参考。Submarine landslide is one of the most destructive submarine geological haz- ards. Once the submarine landslide happens, the slides may travel, with a high speed, a distance of several-tens kilometers, probably even more than hundreds kilometers. The submarine mass movement can pose a great threat to the safety operations of marine en- gineering facilities such as marine oil and gas platforms, submarine pipelines and sea- floor cables. The main purpose of this paper is, based on the latest achievements of re searches on the submarine landslide, to present briefly the research status and advances in survey methods, numerical simulations and physical experiments of the submarine mass movement, thus providing a reference for the further study of evaluation and pre- vention of submarine geological hazards in China.
