摘要
该文介绍了天津某工程在地下障碍物探测的过程中,首先采用大地电导率仪进行面积性盲探,利用电导率信息标定目标体大致水平分布情况,然后采用地质雷达进行详探,根据剖面图谱特征确定其掩埋深度,并结合电导率信息综合推断出障碍物的三维分布情况。工程实例说明,该方法对地下障碍物探测具有效性和准确性,值得在类似工程中推广和应用。
This paper introduces the process of underground obstacle detection in a project in Tianjin.Firstly,the earth conductivity meter is used for area blind detection,and the conductivity information is used to calibrate the approximate horizontal distribution of the target.Then,the geological radar is used for detailed exploration,the buried depth is determined according to the characteristics of the profile map,and the three-dimensional distribution of the obstacles is comprehensively inferred by combining with the conductivity information.The engineering example shows that this method is effective and accurate for the detection of underground obstacles,and it is worthy of popularization and application in similar projects.
