基于GZCORS随探随测的地质雷达人防空洞探测技术研究

Study on air-raid shelter detection technique based on ground penetrating radar with GZCORS

地质雷达具有无损、抗干扰和浅层分辨率高的优势,是城区人防空洞探测最重要的工具之一。传统的外业流程为:先探后测,再返还室内处理和解释数据。这种分离的作业方式常引起成果解释难度大和返工问题。本文充分发挥GZCORS(广州市连续运行卫星定位综合服务系统)快速测量优势,提出了可随探随测及现场解译的新方法,提高了人防空洞探测效率和准确性,最后用工程实例对该方法的优势进行了验证。

Ground penetrating radar(GPR)is one of the most important tool for the detection of air-raid shelters in urban areas because of its outstanding advantages such as the non-destructive,anti-interference and high resolution in shallow strata.The traditional workflow of GPR is to explore firstly and then to measure,and then to return to the indoor for data procession and interpretation.It is worth considering that the separation of the outwork and the inside job,which cause inefficiency,uncertainty and rework of the data interpretation.Based on the advantage of GZCORS′s efficient measurement and high accuracy,the new workflow of the GPR with detecting and measuring simultaneously is proposed.Because of the field interpretation on the GPR data,the new workflow can significantly improve the detection quality and efficiency of air-raid shelters.An example is used to verify the advantages of this new workflow.
