摘要:: Bentley平台为铁路工程建设提供了解决方案，但仍难以完全满足铁路路基设计的专业需求，需采用二次开发的方式建立路基参数化构件库。经研究，提出了基于OpenRail Designer的路基参数化构件库建立的基本流程。研究了构件装配方式、面向对象的设计思路、参数的可变性等多种构件设计方式。对铁路路基构件进行分类，创建构件三维实体模型并附加属性，构件经测试、审核后入库，完成了路基参数化构件库的创建。铁路路基参数化构件库的建立有助于提升路基专业设计建模的效率和质量。

Abstract:: Bentley provides a solution for railway construction, but it is still difficult to fully meet the design needs of railway earthworks, so it is necessary to make secondary development to establish a parametric component library of earthworks. After study, this paper put forward the basic flow to establish a parametric component library of earthworks based on OpenRail Designer. First, three methods of component design were studied, namely the assembly-based components, object-oriented components, and parametric components. Then, the components of railway earthworks were classified, and the 3D solid models with the attributes assigned were established for them, which then were tested, reviewed and put into the library to establish the parametric component library of earthworks. This library will improve the modeling efficiency and quality of the professional design of earthworks.
