公路桥梁三维信息数据库的设计与实现

Design and Implementation of the Highway and Bridge Database with Three-dimensional Information

结合实际的大型公路桥梁项目,分析了基础地理信息和大型桥梁结构的特点,针对数据种类多、数据量大、结构性强以及与三维模型的对接等实际情况,提出了相应的技术路线和方法。同时对比得出桥梁结构表最优的实现方法,并对其具体实现进行了说明。最后,以芜湖长江公路二桥为例建设完成数据库。

Based on actual large- scale highway and bridge projects,it makes the analysis of fundamental geographic information and characteristics of the bridge structure. With the actual conditions of considerable types and volume of data and the strong structural property,as well as the connection with the three- dimensional model,it advises the route of technical application and approach. Besides,through comparison,it gives the optimized approach for achieving the form described bridge structure,and introduces the implementation in detail. Finally,it gives the completion of a database by taking the example of Wuhu Changjiang Highway Second Bridge.
