基于数字孪生的边坡工程及时施工安全控制策略

DT Based Just-in-time Construction Safety Control Strategy for Slope Engineering

摘要:

提出了基于数字孪生（digital twin，DT）的边坡工程“及时（just‐in-time， JIT）”施工安全控制策略。该策略通过引入DT技术，增强对施工过程的感知与响应能力。为提升DT技术在跨专业协同与数据复用中的适应性，进一步构建“场景?实体?关系?事件?控制”（SERIC）建模方法，以支持跨域的信息共享与协同控制。将所提出的JIT施工安全控制策略应用于黄梅山隧道改扩建工程，并融合先进的数据采集、解译与聚合技术，实现对施工状态的动态感知与精准干预。应用结果表明，该策略在提升边坡施工自动化水平、作业效率及安全管控精度方面成效显著。

Abstract:

In this paper， a digital twin （DT） based just-in-time （JIT） construction safety control strategy for slope engineering is proposed. To further enhance the efficiency and precision， DT technology is integrated into the JIT safety control framework for slope construction， and a scene-entity-relationship-incident-control （SERIC） modeling method is introduced for cross-domain sharing and reuse. The proposed JIT construction safety control strategy for slope construction has been implemented in the Huangmeishan Tunnel reconstruction and expansion project， incorporating advanced methods for data acquisition， interpretation， and aggregation. The results demonstrate that the application of the JIT construction safety control strategy significantly improves the automation level， construction efficiency and accuracy of slope construction.
