Research on Applications of BIM + GIS Technology in Bridge Construction

首先分析BIM和GIS的技术特征,指出BIM与GIS的结合能够为桥梁施工过程信息管理提供从宏观到微观的形式展现,更好地实现桥梁施工过程数字化、信息化、可视化建设,进一步提升工程项目施工管理水平。然后,结合桥梁工程施工阶段的需求分析,本文采用C/S系统架构,实现了基于BIM+GIS的桥梁施工进度、质量、成本的三维数字化管理,将数据库技术、桥梁三维参数化建模、数据共享技术应用于桥梁施工过程管理,实现了桥梁施工过程由3D-BIM到5D-BIM的跨越,为管理者提供更有效的决策支持。最后,分析了工程管理信息化实施效果,并指出BIM+GIS技术在工程建设中的应用前景。

This paper firstly analyzes technical characteristics of BIM and GIS,and points out that the combination of BIM and GIS can exhibit the bridge construction process for construction information management,from macroscopic way to microcosmic way.In this way,the bridge construction process can better achieve digitalization,informatization and visualization,which will greatly promote the construction management level of engineering project.Then,considering the demand analysis of the bridge construction stage,this paper adopts the C/S system architecture to realize the3D digital management base on BIM+GIS of bridge construction progress on the project schedule,quality and cost.The system applies database technology,3D parametric modeling of bridge and data sharing technology in the bridge construction process management,and realizesa revolution from3D BIM to5D BIM application in bridge construction,which can offer stronger decision supports to the managers.Last,the implementation effect of project management informatization is analyzed in this paper,through which indicates the application prospect of BIM+GIS technology in bridge construction engineering.
