摘要: 平行地下管线是城市地下管线探测的难点，由于两条管道距离较近，存在电磁场相互叠加的现象，所以使用管线仪无法准确探测管道的位置。通过对管线仪70%定深法的分析，利用计算机模拟地下管线位置与观测水平磁场的关系，结合管线仪和地质雷达探测数据，通过计算机程序模块进行联合反演，得出可视化数据，显著提高了平行管线探测的精度。

Abstract: Parallel underground pipeline is a difficult point in urban underground pipeline detection. Because of the close distance between the two pipelines, electromagnetic fields are superimposed on each other. The use of pipeline meter can not accurately detect the position of the pipeline. Through the analysis of the 70% fixed-depth method of the pipeline instrument, the relationship between the position of the underground pipeline and the observed horizontal magnetic field is simulated by computer, and the joint inversion of the pipeline line instrument and the geological radar detection data is carried out through the computer program module to obtain the visual data and significantly improve the parallel pipeline detection accuracy.
