Abstract
At present, the underground space tunnel in municipal engineering is the advanced layout of technical facilities and pipe network. And it is also the trend of urban construction and development. The main difficulty of underground space tunnel construction is the limited space and complicated pipelines in cities. In the past, during the construction process of metros, utility tunnels and ground crossing signal control, there were pipeline collisions and thus on-site changes are required. Those changes often make local space localized and unreasonable, because of the collision of large-section ventilation ducts. In order to effectively respond to the requirements on promoting the application of BIM (Building Information Modeling) from the Ministry of Housing and Urban-Rural Development, this paper studies the establishment of the visual model of engineering and surrounding environment, the data acquisition mechanism for metro BIM systems, and the collaborative information management platform for metro design based on BIM. The research results have the effect of shortening the construction period, controlling the cost, and ensuring the quality of the design of the utility tunnel. The research results can provide guiding significance for BIM applications on metro design in the future.
