Abstract:Based on CRTSⅢ slab track on a 32 m standard simple-supported girder of high-speed railway bridge, three-dimensional simulation of the paving process and duration was carried out. According to the paving technology of CRTSⅢ slab track on the 32 m simple-supported girder, the paving process was divided into 16 stages. The duration specimen of process was obtained from the construction site of Beijing—Shenyang high-speed railway, and each has 100 groups, which was used to detemine the duration probability distribution of each process. The process and total durations of the track were simulated with Monte Carlo method based on the double codename network plan diagram, thus the total duration probability distribution of CRTSⅢ slab track on a 32 m simple-supported girder was determined. The BIMmodel for track paving which could simulate the duration information was established by Revit software. The results show that it can display the simulation results of duration vividly and achieve the visual management of CRTSⅢ slab track paving process and construction quality archives.

Key words: CRTSⅢ slab track; project schedule; network plan; Monte Carlo simulation; building information modeling (BIM)
