城市三维地下管线定位及埋深探测技术研讨

Research on the Location and Depth Detection Technology of 3D Underground Pipeline in City

根据国土管理部门的业务需要,城市三维地籍测量之地下空间要素的测量工作日益受到重视,地下管线的测量、探测项目不断增多,管线定位、埋深探测技术在城市地下管线基础数据采集和三维数据库建设中发挥着重要的作用。本文介绍了目前地下管线实际应用的几种探测方法,并从应用电磁法探测地下金属管线的基本理论出发,对三种观测系统的定位及埋深探测误差进行了对比和分析。

According to the business needs of land management department,the measurement of the underground space elements of urban 3D cadastral survey is increasingly important. The measurement and detection of underground pipelines are increasing,the pipeline location and buried deep detection technology plays an important role in the urban underground pipeline basic data acquisition and3 D database construction. This paper introduces several methods to detect the actual application of underground pipelines,and the basic theory of the application of electromagnetic method to detect the underground metal pipeline,the positioning of the three observation systems and the depth of the error of the detection error is analyzed.
