CATIA V6在大跨度钢管混凝土拱桥设计中的应用

The application of CATIA V6 in the design of long span concrete-filled steel tube arch bridge

为将BIM技术优势应用于结构复杂的大跨度钢管混凝土拱桥设计中,以计算跨径为565 m的广西平南某桥的设计为例,利用CATIA V6软件建立合理的拱桥三维设计模型,研究经济高效的建模方法及三维可视化应用展示.研究结果表明:将功能强大的CATIA软件应用于拱桥设计全过程,能完美模拟出拱桥特有的线形,可大大提升建模的数字化及可视化程度,提高设计效率;可准确进行工程算量,能模拟施工过程,进行碰撞干涉与误差分析,使设计更加科学准确,提高工程效益.

Takingthe design of the Guangxi Pingnan Bridge as an example,whose calculation span is 565 meters,the paper studies the advantages of BIM technology applied to the complex structure of long span concrete-filled steel tube arch bridge. First,we use the software CATIA V6 to build the three-dimensional model of arch bridge,then,study the economical and efficient modeling method and three-dimensional visualization application. The results are as follows： firstly,the digitization and visualization of arch bridge modeling process can be greatly improved with the powerful application of CATIA V6 software,thus increasing the design efficiency. Secondly,it is the application of CATIA V6 that makes the design more scientific and more accurate,which benefits the engineering a lot for it can simulate the construction process and carry out the collision interference and error analysis.
