新建福厦铁路FX-8标BIM技术应用

Application of BIM Technology in FX-8 Bid of New Fuzhou-Xiamen Railway

本文以福厦铁路FX-8标为例,建立起全标段BIM模型,进行重点工点的方案深化、模拟分析,综合运用CAD、卫星地图、航拍及倾斜摄影模型实现施工前期红线确界、施工干扰调查、前期规划,还开展了隧道三维激光扫描开挖质量控制、喷淋养护、存梁路径优化、运梁模拟、工装设计等方面的应用。针对桥隧的特殊情况开发了形象进度管理和4D模拟模块,研发了建管平台,实现集成管理,提高管理效率,开发了施工监控和拆迁管理等模块,最终集成到智控中心统一维护管理,形成长距离带状工程BIM应用的解决方案。

Taking the FX-8 bid of Fuzhou Xiamen railway as an example,this paper establishes a BIM model for the whole bid section to implement the deepening scheme design and the simulation analysis of the key construction sites.The CAD,satellite map,aerial photography and tilt photography model technologies are comprehensively applied to realize the boundary determination of red line,investigation of construction interference and preliminary planning in the early stage of construction,as well as to achieve the applications of 3D laser scanning in tunnel excavation quality control,spray maintenance,beam storage path optimization,beam transportation simulation,tooling design,and etc.According to the special situation of the bridge and tunnel,the visual progress management and 4D simulation module are developed,as well as the construction management platform,which realizes integrated management and improves management efficiency.The modules of construction monitoring and demolition management are developed and integrated into the intelligent control center for unified maintenance and management,which contributes to the formation of a solution for BIM application of long-distance belt project.
