基于BIM的铁路土建与四电工程接口设计优化

Optimization of Interface Design between Railway Civil Works and Communication,Signal,Power and Electrification Works Based on BIM

随着我国铁路工程建设发展,特别是铁路工程建设标准提高,铁路系统工程建设技术的复杂性,已直接影响到土建、电气化、电力、通信和信号工程等各系统工程在接口设计的质量,以及各系统工程建设的工期和投资。因此,不断优化铁路工程接口设计,达到完善接口工程建设管理的目的十分必要。基于BIM的深化设计集成系统,在新建广湛高铁开展区间场坪、电缆径路优化设计等工作,设计成果主要包括场坪选址、场坪与站前工程冲突、征地面积、过轨位置优化及过轨、上下桥精细化建模,研究基于BIM的深化设计在铁路土建与四电工程接口设计的优化作用。

As the railway engineering construction standards upgrades during the development of railway engineering construction in China,the complexity of railway system engineering construction technology poses higher requirement on the quality of interface design of civil works,electrification,electric power,communication and signal engineering,and affects the construction period of and investment in the construction of all rail system parts.Therefore,it is necessary to continuously optimize the interface design of railway engineering,thus improving the construction management of interface engineering.Based on the BIM-based optimized integration system,we carry out point-by-point inspection and optimization of track,bridge and tunnel engineering design,site selection of communication,signal,power and electrification sections,land acquisition verification,fine modeling of cable built along bridges and crossing over rails in communication,signal,power and electrification sections,and 3D design disclosure in the new Guangzhou-Zhanjiang HSR,and study the optimization role of BIM-based optimization in the interface design between railway civil works and communication,signal,power and electrification works.
