Research on BIM Automated Modeling for Railway Station Based on Digitalized Design System

铁路站场设计是一项复杂庞大的系统工程,应用BIM技术可集成工程项目各种相关信息,形成工程数据模型,实现项目全生命周期中动态的工程信息创建、沟通和管理。然而,当前国内外铁路站场BIM的研究尚处于起步阶段,存在着建模工作量巨大,效率较低的问题。基于此,对铁路站场BIM模型快速构建方法进行了研究,提出基于铁路站场数字化设计系统,可将设计参数信息进行数字化保存,依据参数信息高效驱动铁路站场BIM模型的构建,并对铁路站场数字化设计系统总体架构与BIM模型设计插件的程序模块与流程进行了介绍。通过开发的软件原型系统初步验证,该方法能实现铁路站场BIM模型构建在效率与质量上的双重提升。

Railway station design is a complex systematic project. The application of BIM technology can integrate project-related information,compose project data mode and realize dynamically the creation,communication and management of engineering information in a project life cycle. However,the current research on railway station BIM is still in the early stages with heavy workloads and low efficiency in the modeling. Therefore,the research on the fast modeling method of railway station BIM model is conducted and the digital design system targeting at railway station is presented,with which the parameterized design information could be stored digitally and the BIM modeling of railway station promoted efficiently. In addition,the overall framework of the digital design system of railway station,the program modules and procedures of BIM modeling design plug-in are introduced. This method,which has been preliminarily validated with the system prototype,is proved effective in improving both the efficiency and the quality of railway station BIM modeling.
