摘　　要：浅地层剖面技术广泛应用于浅海灾害地质调查、大陆架第四纪地质调查,也是海洋地质调查的主要手段。海底几千米水深下50~100 m的地层采用浅地层剖面仪可以有效穿透,从而可以探知海底底质情况,比声呐技术测量更具优势。本文通过阐述浅层剖面技术在长江三角洲地层层序划分、沉积过程分析、地质现象分析方面的实践应用,为长江三角洲调查提供技术支撑。Sub-Bottom Profiler survey is an important means for the research of quaternary geology of continental shelf,disaster geology of shallow sea and engineering geology.The Sub-bottom profiler is an important equipment for Marine geological survey at present.The Marine shallow stratigraphic profiler can effectively penetrate the strata of 50~100 m in a depth of thousands of meters,or even deeper,overcoming the limitation of the submarine video system that can only observe the situation of the bottom surface but cannot detect the bottom material below the bottom surface.In this paper,the practical application of sub-bottom profiler in stratigraphic sequence division、sedimentary process analysis and geological phenomenon analysis of the Yangtze River Delta is described,which provides technical support for the investigation of the Yangtze River Delta.
