轨道交通站场BIM设计建模探索

轨道交通站场BIM设计专业软件较为欠缺,为了提高设计效率,统一设计标准及数据格式,基于Bentley的基础图形平台Microstation进行二次开发,对站场设计构件进行对象化、实体化处理,并提出站场股道设计、路基设计、构件设备库等BIM设计方面的技术路线和解决思路。研究表明,在参考股道位置的基础上,软件可自动化生成站场股道、路基、设备等模型;以轻量化数据库对模型信息进行存储,可实现业务模块与既有商业平台的分离与封装,降低设计软件对商业平台的依赖。该研究为实现轨道交通全专业数据互通和正向设计提供一种可行的思路。

Exploration of BIM Design and Modeling of Rail Transit Station Yard

BIM design professional software for rail transit yards is relatively lacking.In order to improve design efficiency,unify design standards and data formats,a graphic platform based on the basis of the Bentley Microstation for secondary development,objectification,materialization was carried out.BIM library aspects including track,roadbed and components were presented.Based on the reference of the location of the stock passage,models including the stock passage,subgrade,equipment were automatically generated.The lightweight database was adopted to store the model information,which realized the separation and encapsulation of the business module and the existing business platform.The dependence of the design software on the business platform was reduced.The study provides a feasible way to realize the full professional data interchange and forward design of rail transit.
