AbstractSubsurface cavity expansion in clay induced by compaction grouting can generate upward displacement of clay and/or increase in effective stress leading to consolidation, resulting in settlement compensation and/or shear strength enhancement respectively. However, the two potential benefits of subsurface cavity expansion may offset each other. Experiments and numerical simulations on the engineering behaviour of E-grade kaolin induced by subsurface pressure-controlled cavity expansion were conducted to investigate the interrelationship between compensation effectiveness and shear strength enhancement. The results of numerical simulations are in reasonably good agreement with the experimental data, indicating that the numerical simulation procedure adopted is a plausible and reliable technique to describe the engineering behaviour of clays induced by pressure-controlled cavity expansion. Effects of cavity expansion rate, cavity expansion volume, injection point spacing, and stress history on compensation effectiveness and shear strength enhancement were studied. Practical applications of the results are also proposed.
