Abstract

Research purposes: To address the challenges in the railway tunnel domain caused by the complexity of original design drawings, which lead to substantial manual interpretation workloads and inefficiencies, as well as the inadequacy of precision and detail in automated modeling processes, this study proposes a 3D analytical modeling method for tunnel drawings based on graphical element matching. The method aims to enable the efficient and automated transformation of 2D drawings into 3D models.
Research conclusions: (1) A graphical element feature extraction method based on Hough Transform is proposed, effectively extracting critical graphical element data from 2D drawings and significantly simplifying the analysis process. (2) Seven geometric constraint conditions are constructed to accurately represent the core parametric relationships of tunnel components, ensuring the high consistency and integrity of the 3D models. (3) A parameterized modeling platform based on WebGL+Three.js is developed, achieving efficient and dynamic visualization of tunnel models, thereby enhancing modeling flexibility and efficiency. (4) The research results can be applied to railway tunnel design, construction management, and digital operations, advancing the intelligent development of infrastructure engineering.
