摘要
本文对地下管线探测的作用、意义、特点等作了简单阐述,介绍了电磁感应法基本原理和具体探测方法,并结合实际案例进行误差对比和应用分析。最后对现阶段电磁法探测技术中存在的不足和测绘新技术发展的方向做了展望。
This article briefly explains the role,significance,and characteristics of underground pipeline detection,introduces the basic principles and specific detection methods of electromagnetic induction method,and combines actual cases for error comparison and application analysis.Finally,the shortcomings of current electromagnetic detection technology and the development direction of new mapping technology are prospected.
