摘要
根据多次的调查资料分析,埕岛海域现在的海底上主要存在5种微地貌形态区即冲蚀地貌区、滑动挤压脊和塌陷凹坑地貌区、侵蚀残留岗丘或台地、斑状海底地貌区、粗糙和平滑海底。三角洲特殊的地貌演化结果对海底管线、座底式平台稳定造成很大危害,在构筑物设计和施工过程中应予以重视。
Based on the survey data in recent years, there are five micro-morphological feature parts in the sea bed of Chengdao area, including erosion morphology, sliding extrusion ridge and collapse, remained scarp or monadnock, blocky seafloor, rough and smooth seafloor, etc. This special geomorphological evolution result will greatly influence the stability of submarine pipeline and bottom-sited platform; it should be pay more attention in designing and constructing of submarine structures.
