摘　　要：结合近年来采集的单道地震和浅地层剖面数据,探讨单一数据在解释工作中存在片面性和精度不足的问题。利用海南岛西部海域单道地震和浅地层剖面仪同步测量数据开展联合解释,分析认为其在划分浅地层结构、识别灾害地质体、圈定海砂资源分布等方面具有更高的可靠性。分析结果显示:在高精度地震资料解释需求的背景下,开展联合解释可有效提高对地质演化的认识,降低地质解释的多解性,优化海砂资源靶区,为海洋开发和海洋工程建设提供更准确可信的地质信息和依据。Based on the data of single-channel seismic and sub-bottom profiles collected in recent years,the is-sues of one-sidedness and inadequacy in the interpretation by single method were explored..Joint interpretation was carried out using single channel seismic and shallow layer profiler synchronous measurement data in the western sea area of Hainan Island,South China.Results show that the joint interpretation has higher reliability in dividing shallow stratigraphic structures,from which disaster geological bodies could be identified,and the distri-bution of sea sand resources be delineated.Under the high demand for high-precision seismic data interpretation,the joint interpretation can greatly improve our understanding of geological conditions,reduce effectively the am-biguity of geological interpretation,and optimize the resource target areas such as marine sand.This study provided a tool for accurate and reliable data interpretation for ocean resource exploration and engineering con-struction.
