Abstract:Most of the existing bridge management systems (BMS) use tables, words and pictures to display information, which results in the poor human-computer interaction experience, thus limits the efficiency of data acquisition and data maintenance. The model generation method of beam bridges based on the B/S architecture is given. The storage fields of component are sorted out. The logical sequence of component is clarified. And the model is correlated with the data. Based on the 3D model, the 3D visual management and maintenance method of bridge detection data is proposed. The function and architecture of each visual module are given in detail to upgrade the bridge management and maintenance levels, and the data utilization efficiency.
