This project aims to investigate the fundamentals of fracture-controlled compensation grouting in various types of soil, so as to optimise the compensation efficiency and to minimise the risk of collapse of nearby structures. This will result in the minimisation of ground movements induced by underground excavations, which pose a major threat to existing infrastructure and communities worldwide. Small-scale laboratory experiments, centrifuge tests and numerical analyses will be conducted to develop an effective and economical grouting method that will provide a valuable design tool for engineers.

本项目旨在研究在不同类型的土体中进行裂隙控制补偿注浆的基本原理，以优化补偿效率，最大限度地降低附近结构的倒塌风险。这将最大限度地减少由地下挖掘引起的地面移动，这对全球现有的基础设施和社区构成了重大威胁。将进行小型实验室试验、离心机试验和数值分析，以开发一种有效而经济的注浆方法，为工程师提供有价值的设计工具。
