摘要
南海北部准被动大陆边缘自第四纪以来具有较强的新构造活动,由此形成的各类潜在地质灾害对于迅速发展的海洋油气勘探开发及沿岸工程建设,是一项值得认真研究的课题。1986─1991年间,首次在南海北部开展的区域性大面积调查和研究成果,将本区潜在地质灾害划分出两大类12种类型,分布于三个不同的区域,内陆架属不稳定区,陆架边缘──上陆坡区是最不稳定的海底。
Since Quaternary period, there is a new strong tectonic movement in quasi-passive continental margin, North Nanhai Sea. All types of potential geological hazard which is thus formed will be a project that is of interest to research conscientiously for development of marine oil and gas exploration in rapid developing and for construction of coastal engineering.During 1986-1991, The regional investigation and research in wide area had been carried out firstly. Based on these results, the potential geological hazards were divided into two categories 12 types, which distribute over three different regions.The inner continental shelf is unstable region, and shelf edage-upper continental slope region is the most unstable sea bottom.
