城市地下管线探测面临电磁干扰、大埋深、地形狭窄等挑战,本文基于Python语言开发地下管线电磁场反演软件。该软件按数据加载、分析、拟合反演、成果展示保存划分模块,构建感应电流磁场水平分量模型,采用最小二乘法反演,结合SciPy库的curve_fit函数实现拟合,以可视化界面展示结果。实例验证表明,软件在近间距平行管线、大埋深及狭窄地形探测中,误差满足现行行业规范《城市地下管线探测技术规程》(CJJ 61—2017)的要求。
Abstract:The detection of urban underground pipelines faces challenges such as electromagnetic interference, large burial depth, and narrow terrain. This paper develops an underground pipeline electromagnetic field inversion software based on Python language. This software is divided into modules based on data loading, analysis, fitting inversion, and result display and saving. It constructs a model of the horizontal component of the induced current magnetic field, uses the least squares method for inversion, and combines with the curve_fit function of the SciPy library to achieve fitting. The results are displayed in a visual interface. Case studies have shown that the errors of the software can meet the accuracy requirements of the industry standard Technical Regulations for Urban Underground Pipeline Detection(CJJ 61—2017) in detecting closely spaced parallel pipelines, large burial depths, and narrow terrain.
