Abstract: The foundation pit safety monitoring platform utilizes the domestically developed BIM software, Railworks, to establish a 3D model, enabling the coding and management of the foundation pit engineering model. It reads the foundation pit data collected by the digital asset management module to drive the creation of a real-time 3D BIM model of the foundation pit, which is synchronized to various management modules for visual application. The platform collects monitoring data transmitted or imported in real-time from various construction monitoring points during the excavation of the foundation pit and the underground construction process. Through data analysis, various change curves and graphs are generated, making the monitoring results "visual" and providing timely feedback. This allows for the prediction of deformation and stability developments that will occur after further construction, achieving informatized construction.
