BIM技术在京张高铁标准梁设计中的应用研究

以Bentley软件为建模平台,创建标准梁的BIM模型,对基于BIM技术的京张高铁标准梁设计进行研究。研究表明:(1)标准梁设计的主要控制要素为几何精度与信息深度;(2)在Bentley软件平台上,可以设定标准梁模型的属性附加项,通过对BIM模型不同类别的属性赋值来承载模型的几何与非几何信息;(3)标准梁的BIM模型主要依靠构件模型控制点的平面位置坐标、高程与方向角进行定位。

Application Research of BIM Technology in Standard Beam Design of Beijing-Zhangjiakou High-speed Railway

The new Beijing-Zhangiakou High-speed Railway carried out BIM design.The Bentley software was used as the modeling platform for BIM design of standard girder in Beijing-Zhangjiakou High-speed Railway.This paper summarizes the key points of the BIM design of the standard girder in the Beijing-Zhangjiakou High-speed Railway.(1)The main control elements of the BIM design of standard girder are geometric precision and information depth.(2)On the Bentley software platform,the attribute additions of standard girder model can be set,thus the geometric and non-geometric information of the model can be carried by assigning values to the different categories of attributes of BIM models.(3)The spatial orientation of the BIM model for the standard girder mainly depends on the plane position coordinates,elevation and direction angle of the control points of the component model.
