针对高速铁路桥梁大规模三维建模的需求，提出一种面向组件的桥梁半自动建模方法。首先对高速铁路桥梁进行组件拆分与子类划分，形成建模的最小构件，采用参数化方法描述构件的几何、定位、材质特征，通过输入参数值获得形态迥异的构件实例；然后根据组件的相互作用规则与定位参数，将组件自动组合为桥梁；最后采用VC 2008语言开发3ds Max插件，在3ds Max平台下实现模型绘制、参数编辑和数据导出。该插件已成功应用于长昆线271座桥建模，取得了良好的应用效果。

According to the demand of large-scale 3D modelling for high-speed railway bridges , we put forward the component-oriented semi-automated bridge modelling method .Firstly, the high-speed railway bridge is divided into components and sub-classes to form the minimum components of modelling .The parametric method is applied to describe the geometrical , positional and material properties of components, the components examples with very different patterns are obtained by inputting the parametric values ; then according to the interaction rules of components and the positional parameters , the components are automatically combined into the bridge;finally, VC 2008 language is adopted to develop the 3ds Max plug-in, and the rendering, parameters editing and data exporting of the model are realised on 3ds Max platform.The plug-in has been successfully applied to modelling 271 bridges in Changkun railway and achieves good application effect .
