Abstract

Digital twins (DTs) offer promising benefits to address several inherent problems in underground construction, yet confusion surrounds the concept due to its context-specific nature which hinders more widespread adoption. This paper seeks to clarify DT-related terminologies from a built environment perspective and define the features and maturity levels of DTs for underground spaces, considering their unique challenges. A layered architecture for constructing DTs is proposed, offering various options based on functionality, technological advancement, and expected value. Additionally, a comprehensive literature review of technologies enabling the development of digital twins for underground spaces is presented, including data-driven ground modelling, site investigation and design process integration with BIM, computational BIM, and advanced sensing and instrumentation. The paper identifies synergies between DTs and the observational method in geotechnical engineering, highlights research gaps, and proposes a transition to a prescriptive, knowledge-based DT. Furthermore, exemplar use cases of underground DTs throughout their lifecycle are explored, demonstrating their potential value.

城市地下空间的数字双胞胎

数字孪生（DTs）为解决地下建筑中的一些固有问题提供了前景广阔的好处，但由于其针对具体环境的性质，围绕这一概念的混淆阻碍了其更广泛的应用。本文试图从建筑环境的角度澄清与数字孪生相关的术语，并考虑到地下空间所面临的独特挑战，定义地下空间数字孪生的特征和成熟度。本文提出了一种用于建造 DT 的分层架构，根据功能、技术进步和预期价值提供了各种选择。此外，还对地下空间数字孪生开发技术进行了全面的文献综述，包括数据驱动的地面建模、与 BIM 相集成的现场勘察和设计流程、计算 BIM 以及先进的传感和仪器。论文指出了地下空间数字孪生与岩土工程观测方法之间的协同作用，强调了研究差距，并提出了向基于知识的规范性地下空间数字孪生过渡的建议。此外，还探讨了地下 DT 在其整个生命周期中的示范性使用案例，展示了其潜在价值。

期刊介绍： Tunnelling and Underground Space Technology is an international journal which publishes authoritative articles encompassing the development of innovative uses of underground space and the results of high quality research into improved, more cost-effective techniques for the planning, geo-investigation, design, construction, operation and maintenance of underground and earth-sheltered structures. The journal provides an effective vehicle for the improved worldwide exchange of information on developments in underground technology - and the experience gained from its use - and is strongly committed to publishing papers on the interdisciplinary aspects of creating, planning, and regulating underground space.
