摘　　要：高速铁路基础设施的状态管理贯穿其全生命周期。因实体要素粒度差距显著、多专业交错复杂等特点致使高速铁路基础设施的状态管理难以高度集约化。解决上述管理痛点的首要基础在于制定适应高速铁路基础设施全生命周期状态管理的编码。为此,本文提出基于数字孪生模型的云编码方式,针对传统编码方式难以实现模型实体与编码深度融合的问题,以高速铁路全域内的基础设施BIM模型为实体要素分类对象,设计具有公有属性与私有属性的云编码规则。以XML树形结构数据作为云编码的存储格式,建立数字孪生模型与云编码的双向映射机制,实现对每一个基础设施的实体赋予唯一、无歧义的身份标识。同时,考虑全生命周期各阶段的业务需求,探究云编码的更新、拓展与实时同步机理,最终形成一体化管理体系。The state management of high-speed railway infrastructure runs throughout its entire life cycle.Due to significant differences in the granularity of physical elements and complex interdisciplinarity,the state management of high-speed railway infrastructure is difficult to be highly centralized.The primary basis for addressing the management pain points mentioned above is to develop codes that adapt to the full lifecycle state management of highspeed railway infrastructure.Therefore,this paper proposes a cloud encoding method based on the digital twin model.In response to the problem that traditional encoding methods are difficult to achieve deep integration of model entities and encoding,a cloud encoding rule with public and private attributes is designed using the infrastructure BIM model of high-speed railways as the entity feature classification object.Using XML tree structured data as the storage format for cloud encoding,this paper establishes a bidirectional mapping mechanism between digital twin models and cloud encoding,and assigns unique and unambiguous identity identifiers to each infrastructure entity.At the same time,considering the business needs of each stage of the entire lifecycle,this paper explores the updating,expansion,and real-time synchronization mechanism of cloud coding,and ultimately forms an integrated management system.
