摘　　要：地下电缆管网精细三维模型是智慧输电建设和管理的重要基础设施。针对当前地下电缆管网精细三维模型建模方法通用性不足的问题,提出一种结合参数化建模和拓扑语义分析的通用自动化重建方法。将地下电缆管网抽象为简单管线、弯管和多通衔接三种拓扑语义,采用Sweep参数化建模、基于空间变换的弯管重建以及基于拓扑语义的多通衔接重建技术,解决了弯管变径和多通衔接的自适应问题,实现了通用地下电缆管网精细三维模型的自动化重建。并结合某地区地下电缆管线数据对方法进行试验,结果显示本研究方法可以准确重建地下管网精细三维模型,为智慧输电中地下管网的精细化管理提供基础支撑。The detailed three-dimensional modeling of underground cable networks is critical infrastructure component for smart power transmission construction and management.To overcome the limitations of existing 3Dmodeling methods,which lack universality,this research proposes a universal automated reconstruction approach that integrates parametric modeling with topological semantic analysis.The method classifies underground cable networks into three topological semantic categories:simple pipelines,bent pipes,and multi-pass connections.It utilizes sweep parametric modeling for straight sections,spatial transformation techniques for bent pipe reconstruction,and topology semantic-based methods for reconstructing multi-pass connections.These techniques address challenges such as adaptive pipe diameter variations and multi-pass connections,enabling the automated reconstruction of detailed 3Dmodels for underground cable networks.The proposed method was evaluated using pipeline data from a specific region,and the results demonstrate its ability to accurately reconstruct detailed 3D models of underground networks.This research provides fundamental support for the refined management and operation of underground networks in smart power transmission systems.
