摘　　要：针对既有建筑数字化工作的资料采集难、建模规范性不足、数据核验难等问题,结合轨道交通项目特点,研究并提出既有轨道交通项目建筑信息模型(building information modeling,BIM)数据化方法。首先,结合运营运维数据需求,提出既有轨道交通项目BIM数据化与场景应用总体框架。其次,研究制定BIM建模交付技术指引,并开发BIM构件标准库,以规范既有轨道交通项目BIM模型创建。然后,结合现场数据采集情况,采取不同方法创建既有轨道交通项目BIM模型。当图纸齐全时,以图纸为基准进行建模;当图纸缺失时,研究以现场图片、点云数据等为基础,通过构件特征识别和匹配BIM构件标准库的构件单元,辅助BIM模型创建。最后,为保障BIM模型质量,研发合标性检查工具,通过内嵌BIM标准规范自动检查BIM模型,并开展现场检查复核各专业BIM模型。目前已在深圳地铁既有运营线路项目开展BIM数据化应用,积累了BIM数字资产,可为其他城市既有运营线路BIM建设提供参考。Considering the problems of the difficult data collection,non-standard models,and inaccurate data in the digitalization of existing buildings,the BIM-based digitalization method for existing rail transit projects was studied and proposed,according to the characteristics of rail transit projects.First,based on data requirements of the operation and maintenance management,an overall framework for BIM digitalization and scenario applications in existing rail transit projects was developed.Second,the technical guideline for BIM modeling and delivery was studied and established,and a BIM component standard library was developed to standardize the creation of BIM models of existing rail transit projects.Third,according to the on-site data collection situation,different methods were adopted to create BIM models of existing rail transit projects.When the drawings were complete,models could be created based on the drawings.When some drawings were missing,the BIM model creation method based on the on-site images and point cloud data was studied through component feature recognition and matching component units in the BIM component standard library.Finally,to ensure the quality of BIM models,a compliance checking tool with embedded BIM standard specifications was developed for automatic model verification.Additionally,on-site inspection was conducted for various professional BIM models.The BIM construction of existing operating lines in Shenzhen Metro is being carried out,accumulating BIM-based digital assets,which provides reference for the BIM construction of existing operating lines in other cities.
