摘要
在海上风电场建设项目中,需要通过勘察活动掌握海底的地层特点以及各种影响施工活动的不利因素。研究过程采用海洋物探法进行海底勘察,经过对比,选用浅地层剖面探测技术。结合具体的工程项目,沿着东西方向和南北方向,布置间距相同的平行测线,将探测系统部署在船舶上,收集海底的回波信号,利用配套软件工具处理相关数据。结果显示,拟建区域基岩面整体埋深较浅,起伏程度较小,并且海底未发现浅层气、油气管线、输电线缆,仅有一条埋藏古河道。以上情况表明,该区域能够为施工活动提供良好的作业条件。
In offshore wind farm construction projects,it is necessary to grasp the geological characteristics of the seabed and various unfavorable factors that affect construction activities through survey activities.The research process used marine geophysical methods for seabed exploration,and after comparison,shallow layer profile detection technology was selected.Based on specific engineering projects,parallel survey lines with the same spacing are arranged along the east-west and north-south directions.The detection system is deployed on the ship to collect echo signals from the seabed,and relevant data is processed using supporting software tools.The results show that the overall burial depth of the bedrock surface in the proposed area is shallow,with small undulations,and no shallow gas,oil and gas pipelines,or power transmission cables have been found on the seabed,with only one buried ancient river channel.The above situation indicates that the area can provide good working conditions for construction activities.
