摘要
该文介绍了地质雷达用于嘉兴海盐县长山河排水泵站海堤抛石层探测,简述了测区地质、地球物理特征、雷达测线布置、探测机理及数据处理流程,分析了雷达反射波同相轴的振幅与频率特性,结合钻孔资料确定了抛石与下伏粘质粉土的分界线,为工程提供了准确的参考资料。
This paper introduces the ground penetrating radar( GPR) is used to seawall riprap layer detection in Changshan river drainage pumping station in Haiyan country Jiaxing city. The geology,characteristics of geophysical,layout of GPR measuring line,detection mechanism and data processing flow are described briefly. Then the amplitude and frequency characteristic of the GPR reflected wave are analysed. At last,the dividing line between riprap layer and underlying clayey silt are determined through analyzing the drilling data. It provides accurate reference data for engineering.
