Abstract: Jingxiong Bridge is a key node project in Jingxiong Expressway project. Because of its unique main arch rib structure, the distortion surface modeling and connection node structure are a great challenge to traditional design and construction mode. This paper rely on the 3DExperience platform, BIM collaborative design and integrated application are carried out, including parametric modeling and structural optimization of design model, deepening design of processing model and integrated application of construction model. Based on the unified model architecture under a single data source, the efficient collaborative application of multi-participants in different places is realized. At the same time, the digital design delivery mode of ' refined model + two-dimensional main drawings ' is explored to reduce the amount of invalid and low-value drawings and improve the integrated application value of the model. Through the deep integration application of the bridge BIM model, it not only effectively solves the design and optimization problems of the spatial distortion surface, but also saves the deepening design time of the processing model for about 4 months, which effectively ensures the implementation progress of the bridge and guarantees the construction quality of the bridge.
