项目摘要

The central requirement of project safety, stability, and resilience of complex underground systems leads to demands for more efficient computational modelling tools to assist design and decision-making during the project life cycle. The concept of Digital Twins (DTs) provides a robust solution to monitor a construction project during its life cycle, predict its behaviour based on integrated holistic computational models, and protect it from hazards by virtually controlling the physical processes with its digital counterpart. Leveraging the power of a computational framework based on CutFEM combined with a BIM platform incorporating CAD-based data, the TwinSSI project will develop a comprehensive DT for underground design and construction. To validate the computational framework, real-scale experiments of tunnel-soil-structure interaction will be performed at the National Buried Infrastructure Facility (NBIF) at UoB. Moreover, the developed DTs will be applied to real case studies co-created with the industrial partners Network Rail and Maidl Tunnel consultants. The TwinSSI project will thus, for the first time, create and validate detailed DTs in the domain of soil-structure interaction modelling. The project outcomes will lead to a new paradigm for project planning and monitoring by geotechnical engineers.

复杂地下系统的项目安全性、稳定性和弹性的核心要求导致需要更高效的计算建模工具来协助项目生命周期中的设计和决策。数字孪生 (DT) 的概念提供了一个强大的解决方案，可以在其生命周期内监控建筑项目，根据集成的整体计算模型预测其行为，并通过与其数字对应物虚拟控制物理过程来保护其免受危险。 TwinSSI 项目将利用基于 CutFEM 的计算框架与包含基于 CAD 数据的 BIM 平台的强大功能，为地下设计和施工开发全面的 DT。为了验证计算框架，隧道-土壤-结构相互作用的真实规模实验将在哥伦比亚大学国家埋地基础设施设施（NBIF）进行。此外，开发的DT将应用于与工业合作伙伴Network Rail和Maidl Tunnel顾问共同创建的真实案例研究。因此，TwinSSI 项目将首次在土壤-结构相互作用建模领域创建并验证详细的 DT。项目成果将为岩土工程师的项目规划和监测带来新的范例。
