Foundation remediation using resin injection.

本研究项目的目的是探索注射膨化聚氨酯树脂作为一种新的选择方案，用于在活性粘性土地基上重新找平和稳定变形的基础。它将确定树脂注射活性粘土基础在浅层和深层注入的物理和行为特征，并将确定该方法的适用性的任何限制。基于详细的实验室和现场测试以及先进的数值模拟，其结果将是能够自信地评估各种活性粘土地基补救策略，并为岩土专业和建筑行业提供亟需的设计指导。

The aim of this research project is to explore the application of injected expanded polyurethane resins as a new option for the re-levelling and stabilisation of deflected foundations on reactive clay soils. It will identify the physical and behavioural characteristics of resin-injected reactive clay foundations, in the context of both shallow and deep injection, and will identify any limitations to the applicability of the approach. Based on detailed laboratory and field testing, and advanced numerical modelling, the outcome will be the ability to confidently assess various foundation remediation strategies in reactive clay soils, and provide much needed design guidance to the geotechnical profession and building industry.
