在分析潮汐通道地区水下滑坡的区域环境的基础上 ,对水下滑坡的分类、结构特征、发育规模和形成时代进行了研究。结果表明 ,本区内的滑坡依据形态特征可以划分为整体性滑坡和破碎性滑坡两类 ,整体性滑坡占绝对优势。多数滑坡具有曲线型滑动面和多级性的特征 ,且绝大多数滑坡发生在全新统中。与陆坡和陆架的其它地区相比 ,因受通道空间的限制 ,研究区滑坡的发育规模相对较小 ,具有与陆上滑坡相似的特征。
Based on the analysis of the regional environment of the underwater landslide in the tidal channel area, the classification, structural characteristics, developmental scale and age of the underwater landslide are studied. The results show that the landslides in this area can be divided into two kinds, one is the whole landslide and the other is the broken landslide according to the morphological characteristics. The landslide takes the absolute advantage. Most landslides have curvilinear sliding surfaces and multi-level features, and the vast majority of landslides occur in the Holocene. Compared with other parts of the continental shelf and the continental shelf, landslides in the study area are relatively small in scale due to the restriction of the passage space, and have the similar features as the land-based landslide.
