轨道交通行业BIM应用背景1.1地铁项目BIM技术应用需求地铁建设是一个涉及多专业的复杂系统工程,除建筑、结构、风水电外,还涉及诸如轨道、机车、信号、环控、消防、自动售检票等多个系统。地铁大部分线路均在市区地下有限空间或较狭隘的地面环境中运行,对设备如何放置和各种管线如何铺设要求极其严格。如果在设计时不能较好地解决这些问题,一旦在施工阶段发现设备无法安装或管线碰撞,一方面会延误工程工期,另一方面将会浪
BIM application background of the rail transit industry 1.1 Subway project BIM technology application requirements Subway construction is a multi-disciplinary complex systems engineering, in addition to construction, structure, wind and hydropower, but also involved such as railways, locomotives, signals, environmental control, fire protection, automatic sales Ticket and other systems. Most of the MTR lines are operated in the urban underground space or in the narrow ground environment, and the requirements on how to place the equipment and how to lay various pipelines are extremely strict. If the design can not be a good solution to these problems, once found in the construction phase of equipment can not be installed or pipeline collision, on the one hand will delay the construction period, on the other hand will wave
