数字孪生在道路工程中的应用综述

The Overview of the Application of Digital Twins in Road Engineering

对数字孪生的基本概念、技术内涵进行了综述,从设计、施工和运维3个不同生命周期阶段对数字孪生技术在道路工程中的应用进行了调研.结果表明:目前数字孪生技术在设计和施工阶段有一定程度的应用,而在运维阶段应用较少.缺少标准规范体系、数据和平台架构不统一、信息化和数字化程度不足以及忽视全生命周期的应用是阻碍数字孪生技术在道路工程中深度应用的瓶颈.因此,规范顶层设计与标准体系、拓展BIM技术的应用以及加强数据的集成、开放和共享是进一步推进数字孪生技术应用的发展方向.

The basic concept and technical connotation of Digital Twins are summarized in this paper.And the application of Digital Twins technology in road engineering is investigated from three different stages:design,construction and operation.The results show that Digital Twins technology has been applied in design and construction stage to a certain extent,but less in operation and maintenance stage.The lack of standard and specification system,the disunity of data and platform architecture,the lack of informatization and digitization,the neglect of the application of the whole life cycle are the bottlenecks hindering the in-depth application of Digital Twins in road engineering.Therefore,standardizing the top-level design and standard system,expanding the application of BIM and strengthening the integration,opening and sharing of data are the development direction of further promoting the application of Digital Twins.
