摘　　要：浅地层剖面探测是海上风电场址勘察阶段中物探调查的重要手段,能有效地探查海底面以下地层结构特征,为风机基础设计、施工及后期运维提供基础资料。通过分析剖面信息采集过程中影响质量的主要因素,研究后处理的过程及关键技术。研究表明:通过异常振幅去除、涌浪改正、多次波压制等数据处理技术,达到了去除干扰波、地质假象,还原海底以下真实地层信息的要求。掌握正确的外业采集和资料处理技术,能消除大部分外界因素对剖面资料产生的干扰及假象,大幅提高浅地层剖面的数据质量,进而更好地服务海上风电场址勘察工作。The shallow stratum profile detection is an important mean of geophysical survey in the survey phase of offshore wind farm sites.That can effectively explore the stratum structure below the seafloor.Provide basic information for wind turbine foundation design,construction,and post-operation and maintenance.The main factors affecting the quality in the process of profile information acquisition,the post-processing process and key technologies were studied and analyzed.The research shows,the requirements of removal of interference waves and geological artifacts,restore the real formation information below the seabed can be achieved by apply data processing technologies such as abnormal amplitude removal,surge correction,and multiple wave suppression.Most of the interference and illusion caused by external factors on profile data can be eliminated by master the correct field acquisition and data processing technology.The quality of shallow profile data can be greatly improved and better applied in wind farm site investigation work.
