Transportation management staff not only need to develop a reasonable program of maintenance in the tunnel after the occurrence of defects, but also need to analyze them in order to constantly improve the daily operation and maintenance plan. However, due to complex interactions and dependency of the tunnel components, , the difficulty of defect analysis increased. Building Information Model (BIM) can realize the integration of all information during the whole life cycle of buildings and thus can make this work come true. In this paper, we combine the tunnel monitoring and maintenance data with BIM data base, using the method of spatio-temporal data mining technology and high-dimensional space-time correlation to analyze the relationship between various components and defects. Finally, the paper evaluates the causes and risk levels and works out decision-making plan. All assets and monitoring information create user-defined visualization and interactive interface guides transportation management personnel to carry out tunnel maintenance with innovative thinking.

In order to solve the the problems caused by diversifed information in the highway tunnel, this article analyzes the characteristics of highway tunnel and uses big data analysis and assessment of BIM technology to study the tunnel maintenance and optimization. Based on the evaluation of the whole life cycle maintenance and optimization decision method, the article describes the basic principle of whole life cycle information evaluation decision and implementation path, and makes strategic choices according to the evaluation results. Finally, innovation points and application effects of this method are summarized, and the future development trend of the tunnel maintenance evaluation is pointed out.

In recent years, BIM technology has been widely used in various engineering areas. The bases of BIM technology are the data standards, and the only way to achieve the goal of sharing information is data standards.The mainstream of BIM data standard is the IFC standard, and this paper draws lessons from foreign experiences in IFC standards as well as the research on IFC standard to define the model view of tunnel engineering construction model and investment analysis model, schedule analysis model and the security analysis model. It provides the basis for the final information sharing in BIM-5D management platform.
