BIM技术在高速铁路四电接口中的深化应用

Deepening Application of BIM Technology in HSR Communication-Signaling-Electric Power-Electrification Interfaces

在高速铁路四电专业设计过程中,传统二维设计手段缺乏对涉及四电专业接口工程内容的深化设计,导致施工过程中出现差错漏碰、废弃工程等现象。利用BIM技术多专业协同设计模式,开展高速铁路四电接口工程建模可视化提资、敷设通道同步深化设计、站前预留工程协调性检查优化及场段综合管线优化设计,可以有效解决传统二维设计四电接口存在的设计深度不够等问题,能够为后续施工建造减少差错漏碰、优化施工流程、避免废弃工程以及交付运维全生命周期管理打下坚实的基础。在项目的实际应用中,产生了较大经济效益,得到了业主施工方广泛认同。

During the design of HSR communication,signaling,electric power and electrification(hereinafter referred to as“four systems”),the traditional two-dimensional solution is short of deepening design in the interfaces of the four systems,resulting in various problems during construction and even abandoned projects.The multi-specialty collaborative design mode of BIM technology is used to realize modeling visualization,synchronous channel laying,coordinated inspection and optimization of reserved civil works,and optimized design of integrated pipelines in yards and depots during the design of the four systems.This solution can overcome the shortage of traditional two-dimensional design,lay a solid foundation for the subsequent construction,optimize construction process,avoid abandoned projects and deliver whole life cycle management of operation and maintenance.In practical terms,the solution yields great economic benefits,and is widely recognized by both the owner and the contractor.
