地下輸電線路之磁場計算必須涵括考量管路空間佈設、相序排列配置及特殊管路排列配置，且需配合不同道路及地下既有管線予以整體分析，若能研發整合各項變數分析於一統整介面，不僅有助於儘早掌握磁場影響，對於設計規劃之可行性提昇，亦有貢獻。
本論文即致力探討低頻地下輸電線路所產生之磁場，並建置模擬介面平台，分析不同輸電線路架構及各種組合下之磁場值，同時適用於實務分析之磁場模擬平台，進而應用探討特殊管路空間佈設及相序排列配置之對應關係，期能有助於瞭解分析地下輸電線路所產生之磁場值，俾供擬定相關決策之需。

In the computation of magnetic field of underground transmission lines, various placements of transmission lines, phase sequences, and special pipelines are all required to include. Moreover, with the consideration of different road configurations as well as existent underground constructions, it has become crucially important to develop an integrated simulation interface such that the influence of magnetic field can be extensively grasped, while the feasibility of transmission line planning will be largely increased.
In view of such an importance, this thesis has devoted to investigating the magnetic field analysis of underground transmission lines with the effort putting on the thorough simulations made under different structures and combinations of transmission lines. The thesis also developed an integrated platform suitable for magnetic field analysis, by which the relationships between pipeline placement and phase sequence are prudently examined as well, anticipating the results gained will be beneficial for a better comprehension of magnetic field under different scenarios and facilitating the decision-making for transmission line planning.
