Preliminary Research and Practical Application of BIM Standard System Framework for Underground Engineering

Abstract

The intelligent transformation has put forward new requirements for the digitization and informatization of underground engineering. BIM can effectively support real feature perception, high-fidelity modelling, virtual mapping, and multi-physical simulation of underground engineering. However, the research on BIM in underground engineering is still in the preliminary exploration stage, and the standard system framework, key theories and technical directions are still not clear enough. Based on literature research, the current status of BIM standard system was analysed, and the preliminary framework for the BIM standard system combined with the characteristics of underground engineering and the needs of intelligent transformation has been established. According to the compilation principles, the standard system framework was divided into three parts: data standards, application standards, and management standards, and the composition of each part has been studied. The applicability of this framework has been demonstrated through an underground engineering example. The aim is to provide reference for the development of BIM theory and technology in underground engineering, and promote the full lifecycle digital information application of underground engineering.
