Research and development of tunnel intelligent design system

Abstract According to the characteristics of tunnel design, the tunnel BIM entity is created based on the digital ground model, forming a set of data sources, two-dimensional drawings, three-dimensional models and three expression design forms of BIM building information. The system can complete the design of tunnel building boundaries and internal contours, tunnel lining design, cave door design and auxiliary construction measures design; Among them, intelligent design is a feature of the software: the design of the cave door, lining section and auxiliary measures can be intelligently determined through the information such as the type of surrounding rock and the burial depth of the tunnel in the geological data, so as to realize the digitization and intelligence of the tunnel design. In addition, there is a template library function, a timely update function. At present, the system can meet 80% of the business needs of tunnel design, which greatly improves the design production efficiency.
