Fundamental study of fracture-controlled compensation grouting for ground movement

本项目旨在研究不同类型土壤中的可控补偿灌浆的基本原理，以优化补偿效率并将附近结构倒塌的风险降至最低。这将使地下挖掘引起的地面移动最小化，地下挖掘对全球现有基础设施和社区构成重大威胁。通过小型室内试验、离心试验和数值分析，研究出一种经济有效的灌浆方法，为工程师提供有价值的设计工具。

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.
