Current methods for calculating urban rail transit underground structures face challenges, including those associated with low modeling efficiency, redundant data entry, and time- and labor-intensive calculation report compilation. To address these issues, the authors analyze the computational workflow of the main structures and existing methodologies, proposing a functional framework for an automated whole-process calculation platform. Based on unified component coding rules, data integration is achieved for geological information matching, cross-sectional information configuration, load information configuration, finite-element modeling and analysis, and component and reinforcement verification. Moreover, the structural storage of whole-process calculation data is synchronized, and the automated generation of calculation reports is supported. A finite-element automated modeling and calculation method for rectangular frame structures driven by the characteristic parameters of calculation cross-sections is also presented. This method details technical principles for whole-process automation, including the development of multitype calculation model elements in SAP2000, model element assembly, meshing, boundary conditions, and load application, as well as computation and result output. An automated calculation platform for rail transit underground structures, comprising cloud computing modules and SAP2000 desktop plugins, is developed. The platform achieves fully automated workflow computation, enables one-click generation of calculation reports, and facilitates coordinated generation of reinforcement detailing drawings and three-dimensional models for typical cross-sections via Revit integration. Application in multiple design projects demonstrates that the platform meets design accuracy requirements while improving efficiency by >80% compared to conventional design approaches.
