摘要
近年来,随着城市化进程的加速,地下空间的建设和利用日益复杂,但由于管道的老化、损坏及施工误伤频发,对其精准探测与管理提出了更高要求。下文基于磁法勘探技术,研究其在城市地下金属管道的探测能力,综合磁分量、磁异常、磁梯度进行分析和精确定位,并在工程案例中通过地面磁测数据与井中磁梯度法进行验证。研究表明,该方法具有高灵敏度和较强的探测能力,在能源管道的精确定位中表现出显著优势。
In recent years,with the acceleration of urbanization,the construction and utilization of underground space have become increasingly complex.However,due to the aging,damage,and frequent construction errors of pipelines,higher requirements have been put forward for their precise detection and management.This article is based on magnetic exploration technology to study its detection capability in urban underground metal pipelines.It comprehensively analyzes and accurately locates magnetic components,magnetic anomalies,and magnetic gradients,and verifies them through ground magnetic survey data and wellbore magnetic gradient method in engineering cases.Research has shown that this method has high sensitivity and strong detection capability,demonstrating significant advantages in precise positioning of energy pipelines.
