Abstract

Existing methods for patch repair in masonry tunnels are time-consuming, heavily reliant on manual labour, and inadequate to address the maintenance needs of the UK’s ageing Victorian railway tunnel network. This paper proposes a systematic framework to define innovative automated repair strategies by amalgamating various repair concepts, manufacturing techniques, and materials. Through this framework, the study examines 38 feasible alternatives, incorporating approaches such as robotic spraying, additive manufacturing, automated cutting, and the utilisation of advanced cementitious materials and composites. A thorough sustainability assessment, covering environmental, economic, social, and technical dimensions, guides the identification of the most appropriate repair solution. This assessment involves simplified process analysis, cost evaluation, life cycle analysis, and layered analysis, all integrated into a multicriteria decision-making (MCDM) methodology to derive a comprehensive sustainability index.

新型砌体隧道自动修复方法：可行性和可持续性

现有的砌体隧道修补方法耗时长，严重依赖手工劳动，不足以满足英国维多利亚时代老化的铁路隧道网络的维护需求。本文提出了一个系统的框架来定义创新的自动化修复策略，通过合并各种修复概念，制造技术和材料。通过这个框架，该研究考察了38种可行的替代方案，包括机器人喷涂、增材制造、自动切割以及先进胶凝材料和复合材料的利用等方法。全面的可持续性评估，涵盖环境、经济、社会和技术层面，指导确定最合适的修复解决方案。该评估包括简化过程分析、成本评估、生命周期分析和分层分析，所有这些都集成到多标准决策（MCDM）方法中，以得出综合可持续性指数。

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.
