摘　　要：某海上风电场的拟建区域约为4600m^(2),为了避免施工活动破坏海底油气管道或者输电线路,需要综合运用多种物探仪器检测拟建区域及周边海床的路由管线。研究过程采用多波束声呐系统测量海水深度,判断拟建区域的地形地貌。再使用磁力仪检测作业区东北侧既有输气管道的路由偏距,发现其远离施工范围。最后联合运用磁力探测和浅地层剖面探测技术,对拟建区域地层结构及地下设施进行检测,未发现管线设施,满足施工条件。The proposed area of a certain offshore wind farm is about 4600m^(2).In order to avoid construction activities damaging submarine oil and gas pipelines or transmission lines,it is necessary to comprehensively use various geophysical instruments to detect the routing pipelines in the proposed area and surrounding seabed.The research process uses a multi beam sonar system to measure the depth of seawater and determine the terrain and topography of the proposed area.Using a magnetometer to detect the routing deviation of the existing gas pipeline on the northeast side of the work area,it was found that it is far from the construction area.Finally,a combination of magnetic detection and shallow geological profile detection technology was used to inspect the geological structure and underground facilities in the proposed area,and no pipeline facilities were found,meeting the construction conditions.
