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了对更有效的计算建模工具的需求，以在项目生命周期内协助设计和决策。数字双胞胎（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，基于集成的整体计算模型预测其行为，并通过虚拟控制其数字对应的物理过程来保护其免受危害。利用基于CutFEM的计算框架的强大功能，结合包含CAD数据的BIM平台，TwinSSI项目将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的实验将在UoB的国家地下基础设施（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的案例研究。因此，TwinSSI项目将首次在土-结构相互作用建模领域创建和验证详细的DT。项目成果将为岩土工程师的项目规划和监测提供一个新的范例。
