Abstract: In order to further study the BIM application in railway tunnel in terms of construction schedule, safety and quality, a BIM construction management platform is developed by BIM, EPC system network and other technical means for Gaoligongshan Tunnel on DaliRuili Railway, and based on which the BIM application researches including progress dynamic control, multidimensional calculation, risk management and quality monitoring are carried out. The results show that: (1) The BIM application in terms of schedule management and multicalculation comparison of quantities realizes the viewing, analysis and early warning of tunnel schedule information, and solves the problem of inaccurate traditional calculation. (2) The application of BIM risk management vividly shows the state of surrounding rock, adverse geological risk points and features, the number and distribution of personnel in the tunnel, which can ensure the personnel safety and reduce risk during tunnel construction. (3) The BIM+3D laser scanning, TBM tunneling parameter control and other methods are used to control quality during tunnel construction, and the problem labels are identified and finally the database with safety and quality problems of Gaoligongshan Tunnel is formed to realize the traceability of safety and quality problems.
