This invention discloses a method and storage medium for intelligent analysis and construction of temporary roads based on BIM technology, aiming to solve the problems of existing technologies relying on manual labor, low planning efficiency, and lack of dynamic analysis capabilities. The method first acquires topographic point cloud, historical traffic flow, and obstacle information of the construction area through multi-source data collection, and constructs a 3D BIM scene integrating terrain, road network, and obstacles. Then, based on preset start and end points and road layout areas, the system automatically generates a 3D model and preliminary plan for the temporary road using built-in algorithms and a parameterized family library. Next, dynamic simulation analysis is performed using historical traffic flow data to optimize road parameters and complete collision verification, outputting a file package containing the model, analysis report, and construction parameters. Finally, visual construction guidance is provided via a mobile terminal. This invention achieves intelligent management of the entire process from data to construction, significantly improving the accuracy, efficiency, and economy of temporary road planning.
