南海是我国海洋开发的重点海区之一, 调查潜在地质灾害因素, 科学地评价海洋工程地质条件至关重要。本文根据20多年的调查资料, 研究了南海可能产生的地质灾害类型、规模、分布特征、形成机制和诱发因素, 分析了南海地质灾害因素主要特征, 提出今后研究方向, 为科学开发海洋资源提供依据。
South China Sea is one of the significant marine development areas in China. It is very important to evaluate scientifically the marine engineering geological conditions on the basis of research on various factors for geologic hazards. The potential factors for geologic hazards are the essential causes of geologic hazards. They not only affect the process of marine oil exploration and development, but also cause a lot of unexpected economic loss in submarine engineering operations. This paper studies the types, size distribution, formation process, and inducing factors for possible geolgic hazards, on the basis of practical surveys in South China Sea more than 20 years. The practical measures for preventing geologic hazards are suggested in order to provide a foundation for the development of sea resources.
