隨著3D技術的發展，公共管線圖資已從平面展示進展到三維化呈現，然而在管線衝突分析使用的方法仍為擷取管線管徑寬、高及管頂高等相關屬性資料來進行運算，得到的結果也僅能顯示衝突處的中心點而非3D多形體，在實務應用上可能因不夠精確造成誤判情形，因此本研究旨在建立一套完整的三維管線衝突分析自動化流程，並依據分析結果作為非破壞性檢測的實行順序參考，以提升圖資正確性。
首先本研究回顧了公共管線的發展歷史、目前管理的狀況，及目前三維管線的建置方式。接著本研究提出三維管線衝突分析的自動化流程，針對不同管線設施類型，設計不同的三維模型轉置方法，該方法可依據紀錄於公共管線的屬性資料進行三維管線模型的建置，並將轉置後成果進行衝突分析，供決策者參考及後續應用。
在研究成果部分，本研究選定兩個區域，一為具有大範圍實測資料的重劃區，二為原圖轉繪資料居多的舊市區住宅區，實際進行衝突分析，並進行成果的展示與相關數據的統計。
透過本研究的衝突分析自動化流程，可獲得精確的三維形體衝突分析成果，減少重複性圖形化介面操作並大幅縮短作業時間。在效益部分，本研究取電信、電力、自來水等三大類管線類型，各一筆管線及一筆人手孔進行分析，人工操作GIS軟體所需時間約20分鐘，而透過本研究的自動化分析程式需花費6分鐘，相較於人工操作可減少約70%的時間，且可排除人為操作導致的錯誤。後續可應用於設計資料檢查、實測資料審查、非破壞性檢測施行順序決策、道路挖掘申請等方面。

With the advancement of 3D technology, Public Utility Pipelines has evolved from flat displays to three-dimensional presentations. However, methods for pipeline intersect analysis still rely on extracting relevant attribute data such as pipeline diameter width, height, and top height for computation. The results obtained can only show the center point of the conflict rather than a 3D polyhedron. In practical applications, this may lead to misjudgments due to insufficient accuracy. Therefore, this study aims to establish a complete automated process for 3D pipeline intersect analysis and use the analysis results as a reference for the sequence of non-destructive testing implementations to improve the accuracy of the Public Utility Pipelines data.
First, this study reviews the development history of Public Utility Pipelines, the current management status, and the current methods of constructing three-dimensional pipelines. Then, this study proposes an automated process for 3D pipeline intersect analysis. Different three-dimensional model transformation methods are designed for different types of pipeline facilities. This method can construct three-dimensional pipeline models based on the attribute data recorded in the public pipelines and perform intersect analysis on the transformed results for decision-makers' reference and subsequent applications.
In the research results section, this study selects two areas: one is a redevelopment area with extensive survey data, and the other is an old residential area in the old city with mostly not measured data. Actual intersect analysis is conducted, and the results are displayed and relevant data are statistically analyzed.
Through the automated intersect analysis process presented in this study, precise three-dimensional shape intersect analysis results can be obtained, significantly reducing repetitive graphical interface operations and greatly shortening operation time. In terms of benefits,This study analyzes one pipeline and one manhole from each of the three major pipeline types: telecommunications, electricity, and water supply. Manual operation of GIS software takes approximately 20 minutes, whereas the automated analysis program developed in this study takes 6 minutes, reducing the time by about 70% compared to manual operations and eliminating errors caused by human operation. This process can be applied to design data inspection, survey data review, non-destructive testing implementation sequence decision-making, road excavation applications, and more.
