地质雷达探测地铁沿线未知涵洞的研究与应用

以某在建工程线路经过老城区主干道的地质与环境调查为研究对象,采用地质雷达探测方法,在路面合理布设探测剖面和观测系统;通过对采集的地质雷达记录进行有效处理和地质雷达图像的分析,研究如何在地铁隧道勘察中根据场地条件和探测的目标物,综合识别未知涵洞.研究结果表明:通过设计纵横跟踪布设地质雷达探测剖面,选择恰当的资料处理参数和...

Research and application of geological radar to detect unknown culverts along roadsin subway construction

The geological radar detection technology has a good effect in the investigation of underground pipelines, culverts, residual piles and other abnormal objects in urban underground engineering, and provides effective technical support for the survey work near the ground. This article takes the geological and environmental survey of a subway line under construction passing through the main road of the old city as the research object, adopts the method of geological radar detection, lays out the detection profile and observation system on the pavement reasonably, through the effective processing and geological radar of the collected geological radar records Image analysis to study how to comprehensively identify unknown culverts based on site conditions and detected targets in the subway tunnel survey. The research results show that: by designing horizontal and vertical tracking and laying geological radar detection profiles, and selecting appropriate data processing parameters and modules, the specific location and scale of unknown culverts can be effectively detected, reasonable suggestions for engineering design and construction are proposed, and construction risks are greatly reduced.
