摘要

研究目的：针对当前铁路行业内建设铁路BIM所存在的“拿来主义”及分割立项的现象，从信息技术与空间认知的角度揭示铁路BIM区别于建筑BIM的区别，针对性地提出铁路信息模型(RIM)的概念，剖析各阶段RIM的主要应用特征，并基于实际调研提出建设RIM的基本原则。

研究结论：（1）铁路RIM与建筑BIM存在本质区别，RIM需要建立在数字地球空间进行表达，才能具备空间一致性、系统完整性，才具备全生命周期的长度价值与普遍适应的应用广度；（2)RIM的建设要遵从：基础平台建设→数字化铁路→标准规范→业务应用RIM平台，做好顶层设计，避免不必要的建设浪费，有序推进的实施路线开展；（3)从数据资源优势与综合技术优势来讲，铁路设计企业最具备承担RIM的建设条件并提出总体解决方案与行业标准规范；（4)本研究成果可为当前铁路RIM的建设提供指导作用。

Abstract：Abstract：Research purposes： As phenomenon for inappropriate copinism and separatist on building BIM at present in railway industry, from professional view of information technology and spatial cognition, we revel the misunderstanding of railway BIM building which significantly different from architectural BIM. The concept of RIM is proposed to distinguish from BIM, and then we dissect its main features at different stages and put forward the basic construction principles for RIM. Research conclusions：(1) Essential difference hinder interoperability between BIM and RIM. RIM should build on digital earth space in order to guarantee consistency space and system integrity, only in this way can guarantee the full life cycle application and universal adaptability at all depth and breadth. (2) RIM's construction should follow the line steps of basic RIM platform→digital railway product→application standards→application RIM, do good top-level design to avoid unnecessary waste and orderly carry out the implementation of RIM. (3) In terms of its advantages on comprehensive technical and data resources, railway design enterprises have the best conditions to shoulder RIM platform construction and then bring forward total solutions and industry standards for RIM. (4) This research provides an active role in guiding the current hot RIM railway construction.
