Study on underground engineering auxiliary planning and design technology based on BIM+GIS

Engineering Planning is the primary task of underground engineering. The planning dimension of underground engineering still remains at the two-dimensional level, lacking a technical platform for processing and analyzing multi-dimensional and multi-source information. Especially due to insufficient information under hidden geological conditions, the quality of subsequent design and construction cannot be guaranteed. BIM+GIS can achieve the unification and technical application of data at the macro scale and three-dimensional models at the micro scale. Therefore, based on BIM+GIS, the technical architecture of an underground engineering auxiliary planning and design platform was established, Taking the underground pipe gallery project as an example, simulation analysis was conducted A comprehensive model integrating engineering and three-dimensional geology has been established. Based on the three-dimensional spatial conflict analysis results of geological and underground pipe gallery engineering, optimization design was carried out. The research results can clearly demonstrate the correlation between underground pipe gallery engineering and geographical environment, enabling planners to carry out planning and design work from both macro and micro perspectives, improving the technical level of planning and design, and providing new avenues for innovation in underground engineering planning and design technology.
