利用地质雷达求取地下目标物体积研究综述（增刊）

随着地下空间等资源的大规模开发,无损探测等新技术在地下空间的应用不断发展,特别是地质雷达的应用越来越普遍。对地质雷达的基本原理进行了简述,介绍了国内外对地质雷达技术的应用与相关研究。国内学者将无损探测技术应用于对地下物体体积的探究,并取得了可以满足工程实际需要的成果。利用地质雷达求取目标物体积研究主要有两个思路,一是通过理论研究导出体积计算公式,二是利用地质雷达进行多次测量绘制出目标物的外形轮廓,用等效的方法得到计算体积的模型。提出了在探测过程中物体遮挡情况会对探测影像的显示产生影响,从而对目标物体积的求取产生影响。本文针对上述问题提出了初步研究思路和进一步研究的展望。

Overview of the Study on the Volume of Underground Target by Using of GPR

With the increase in the utilization of existing space resources, non-destructive detection technology and other new technologies in the underground space exploration process continue to develop, especially in geological exploration of GPR applications more and more common. The basic principles of the GPR are reviewed, and the applications and related researches of the GPR instrument at home and abroad are also introduced. Some domestic scholars use the nondestructive detection technology to the exploration of the volume of underground objects and the achievements that can meet the actual needs of the project. The researches on the use of GPR to obtain the target volume are divided into two types: The volume calculation formula is derived from the theoretical research, the second is to use the GPR to measure the outline of the target object, and the model of the calculated volume is obtained by the equivalent method. It is proposed that the object occlusion situation will affect the display of the detected image during the detection process, so as to influence the target volume. This paper puts forward the preliminary research ideas and the prospect of further research on the above problems.
