Abstract

Based on geophysical survey and Marine geological data, the characteristics of seabed topography, stratum structure and geological structure in the Caofeidian deep trough area are studied, and the formation reasons and influencing factors of topography and geomorphology in the caofeidian deep trough area are analyzed. Based on H6 borehole data, it is determined that the regional stratigraphic age is from Holocene to Late Pleistocene, and three transgressions occurred. Geo-slope analysis software is used to calculate the stability of submarine SLOPE quantitatively, and the stability of SLOPE under extreme conditions such as large wind wave and earthquake is simulated and analyzed. It is concluded that if the intensity of the tangshan earthquake occurs, the seabed slope will have a large deformation and the overall instability may occur. Engineering measures can be used to restrain the deformation of the seabed slope and structures and prevent the seabed geological disasters caused by the earthquake. The results of the project can be applied to other areas of the ocean and coastal zone.
