摘　　要：随着工程建设的发展,近距离大埋深地下管线的探测成为当前工程领域的难点。针对近距离大埋深金属管线探测,本文研究了水平电磁剖面法,首次提出了间接充电法信号加载方法,并采用了带地形改正的磁感应强度反演方法。文章结合一个多条近距离敷设埋深大于12m的地下管线探测实例,详细阐述了探测过程中的关键技术及解决方案。探测结果经人工开挖验证,完全符合实际,精度满足要求,可为类似工程提供参考和借鉴。With the development of engineering construction,the detection of close range and deep buried underground pipelines has become a difficult point in the current engineering field.For the detection of close range and deep buried metal pipelines,the horizontal electromagnetic profile method is studied in this paper,the indirect charging method for signal loading is proposes for the first time,and the inversion method of magnetic induction intensity with terrain correction is adopted.The key technique and solution is presented in detail which is applied in a detection project of multiple underground pipelines buried more than 12m depth and in close distance.The detection results have been verified by manual excavation and are fully in line with reality.The accuracy is satisfied with the requirements.It can be referred by the similar projects.
