日照市近海海域灾害地质类型及特征分析
|
摘要
日照近岸海域灾害地质类型主要为埋藏下切谷、海底侵蚀、冲刷沟槽和冲刷陡坎及海底抛泥区等。通过对日照海岸带近岸海域的浅地层剖面和水深测量资料,开展主要地震地层界面的追踪和对比,结合沉积物粒度和地球化学特征,对近海海域潜在灾害地质因素进行分析对比,探讨了日照近海海区的灾害地质类型、特征和分布规律,为半岛蓝色经济区的海洋开发提供基础地质资料。
Types of geological hazards in offshore area in Rizhao city are mainly buried incised valley,submarine erosion,erosion groove,erosion scarps and seabed spoil area,etc.Based on shallow stratum profile and bathymetric survey of offshore areas in Rizhao city,main seismic stratigraphic interfaces have been traced and contrasted.Combining with sediment grain sizes and geochemical characteristics,potential geological hazard factors in offshore areas have been analyzed and compared.Types,characteristics and distribution of geological hazards in offshore areas have been discussed.It will provide basic geological data for ocean development in Peninsula Blue Economic Zone.
