Integrated analysis of the marine geological environment and hazards in the Dapeng Bay

Abstract：Integrated investigation and research on the marine geological environment and hazards in the Shenzhen sea area of the Dapeng Bay were carried out by the Guangzhou Marine Geological Survey. According to the data of seawater chemistry, seafloor sediments and seabed engineering geological conditions (including potential geohazards) obtained during the investigation, combined with surveys of seafloor topography and geomorphology, single-factor evaluation and multi-factor integrated evaluation were made of the marine geological environment in the bay. According to the evaluations, the authors think that on the whole the marine geological environment in the Dapeng Bay is good. Then valuable suggestions about marine development engineering construction in the Dapeng Bay are put forward.
