摘要:
目的：城市轨道交通作为新型基础设施的重要组成部分，建设规模大、专业种类多、资料归档困难，数字化交付作为建筑工程信息化的重要环节，也是数字孪生与元宇宙领域重要的底层基础数据载体，可以有效解决传统以纸质资料为媒介的竣工归档交付中资料缺失、信息不准确、运营期检索资料困难等问题。通过基于BIM(建筑信息模型)技术的数字化交付可以提高项目和企业信息化管理效率，推动建筑业现代化进程。方法：在现有数字化交付研究基础上，聚焦城市轨道交通行业，系统研究了基于BIM技术的数字化交付实施规划、交付流程、关键技术解决方案及数字化交付平台应用，对影响数字化交付的实施范围、建模要求、属性信息维护、构件编码、轻量化引擎等关键技术节点逐一实践。结果及结论：通过实际工程项目应用，验证了城市轨道交通类项目数字化交付的可行性，总结了基于BIM的数字化交付实施过程中的特点和难点，并提出了相应技术解决路径的优化方向。

Objective: As an essential component of new infrastructure, urban rail transit projects are characterized by their large construction scale, diverse disciplines, and data archiving difficulties in. Digital delivery, as a crucial part of construction project informatization, serves as a fundamental data carrier for digital twins and metaverse field, effectively addressing issues such as missing data, inaccurate information, and difficulties in retrieving operation period documents in conventional paperbased completion and delivery process. Through digital delivery based on BIM (building information modeling) technology, the project efficiency and enterprise informationoriented management can be improved, driving the modernization process of the construction industry.Method: Based on existing research on digital delivery, focusing on the urban rail transit industry, a systematic study is conducted on the implementation plan, delivery process, key technology solution schemes, and platform application of digital delivery application based on BIM technology. Key technical aspects that impact digital delivery including the implementation scope, modeling requirements, attribute information maintenance, component coding, and lightweight engine are examined through elaborative practices.Result & Conclusion: Through practical engineering project application, the feasibility of digital delivery in urban rail transit projects is verified. The characteristics and challenges of implementing BIMbased digital delivery are summarized, and corresponding optimization direction for technical solutions is proposed.
