摘　　要：铁路建设是我国重要的基础建设项目之一,正处于新一轮的建设高潮。传统地形测绘对于复杂铁路线路环境具有局限性,利用BIM技术的可视化、可模拟性等特性能够克服该局限性。本文研究基于BIM技术的铁路线路建模方法,应用参数化建模理论,将模型特征和内部规则参数化,以铁路桥梁和道岔为建模对象,建立三维模型及模型间的信息关系。通过创建不同类型铁路线路的参数化BIM模型及装配方法,实现铁路线路的三维表达与工程信息化。Railway construction is one of the important infrastructure projects in China,which ushered in a new round of construction climax.Traditional topographic mapping has limitations for complex railway line environ-ment,which can be overcome by using BIM technology's visualization,simulation and other characteristics.This paper studies the method of railway line modeling based on BIM technology,applies the theory of parametric modeling,parameterizes the model features and internal rules,takes railway bridges and turnouts as modeling objects,and establishes three-dimensional models and information relationships between models.By creating par-ametric BIM models and assembly methods for different types of railway lines,three-dimensional representation and engineering informatization of railway lines are realized.
