基于BIM的铁路封闭式路堑设计研究

为了提高封闭式路堑的设计水平，实现工程数字化管理，开展基于建筑信息模型（BIM,Building Information Modeling）的铁路封闭式路堑设计研究。介绍其设计流程和方法，以及与隧道、桥梁接口的深化设计，钢筋深化设计及综合碰撞检查。该设计方法已在多个铁路工程项目中应用，有效减少了设计盲区及专业间的错漏碰缺，提高设计效率和质量，可为其他铁路封闭式路堑设计提供参考。

Design of railway closed cutting based on BIM

In order to improve the design level of the closed cutting and implement the digital management of the project, this paper carried out the research on the design of the railway closed cutting based on Building Information Modeling (BIM). The paper introduced the design process and method, the deepening design of railway closed cutting and tunnel bridge interface, the deepening design of reinforcement and comprehensive collision inspection. This design method has been applied in many railway projects. The application of this method effectively reduces the design blind area and the errors, omissions, collisions and defects between specialties, improves the design efficiency and quality, and can provide a reference for other railway closed cutting design projects.
