摘要
根据大量地质-地球物理实测资料,分析研究了南海东北部海底潜在的地质灾害因素,特别是海底滑坡与崩塌、活动断层、沙波与沙丘、陡坎与断裂谷、埋藏古河道与古三角洲、侵蚀沟谷及海底峡谷等与海洋工程关系密切的地质灾害的类型、分布特征、形成机制及危害性,为海洋开发与海底工程设计提供科学依据。
According to a vast amount of investigation data acquired by geological and geophysical methods, types, distribution features, formation mechanisms and harmfulness of various kinds of potential sub- botttom geological hazards in the eastnorthem South China sea , especially landslide and collapse, ac- tive fault , sand wave and sand dune, steep ridge and fault valley, buried paleochannel and paleo- dalta, erosion groove (valley) and subbottom narrow which are closely linked to marine engineering, are analyzed so to provide scientific basis for developing marine and designing seafloor engineering.
