摘要:
埕岛海区处于特殊的地理位置,是海底地质灾害频发地带,因而直接威胁到海上工程设施的安全。过去多限于对某些重点区域有针对性的声学探测和实测资料的解释,通过收集20多份井场调查资料,对埕岛海区浅地层地质灾害按水深进行分类,并对成因进行分析。结果表明,5 m等深线以浅多冲蚀沟槽;8～12 m地质灾害体类型较多;12～16 m多为充填相地层。

A study on factors of geological hazards in Chengdao shallow stratum
Abstract:
Based on the especially geography situation, Chengdao area is typically characterized by geologic hazards,which will threaten the safety of the offshore engineering. Many investigations were carried out in this area only limited to the measurement of geologic hazards using the sonic equipment and the records were interpreted. Here the data of more than 20 well sites in this area are collected to analyze the related geologic hazards. The distribution of the shallow stratum geologic hazards is presented according to water depth. Bellow the 5 m isobaths mild erosional furrows were developed; between 8 m and 12 m isobaths there are many geologic hazards;between 8 m and 12 m isobaths geologic hazards are mostly filled facies stratum.
Key words:  Chengdao sea area  shallow stratum  geological hazards
