宁波中兴大桥及接线工程BIM设计与应用

宁波中兴大桥为目前全球最大跨径的单索面矮塔斜拉桥，大桥建设条件苛刻、桥梁构造复杂、施工场地有限。项目从方案设计开始使用自主开发软件进行BIM正向设计，采用倾斜摄影、虚拟现实等技术，在国内大型市政桥梁工程中首次实现了倾斜摄影与BIM技术的融合，采用多款软件对BIM模型进行了性能分析和设计方案优化，为BIM技术的应用拓展打下良好的基础。

BIM Application in the Design of Ningbo Zhongxing Bridge and Connection Engineering

The Ningbo Zhongxing is a cable-stayed bridge with single-cable-plane and low-tower, which possesses the largest span currently in the world. The construction condition of the bridge is harsh, the bridge structure is complex, and the construction site is limited. From the very beginning of the design phase, the projects starts adopting the independent developed software for the BIM forward design, which employs modern technologies including the tilted photography and virtual reality. This is for the first time that the integration of tilted photography and virtual reality is applied in the construction of domestic large municipal bridge project in China. The performance analysis and design optimization of the BIM model are carried out with a variety of software, which lays a good foundation for the application of BIM technology and its future development.
