Geotechnical Earthquake Engineering and Soil Dynamics V
A Study into Resin Injection as a Ground Improvement Technique for Seismic Liquefaction Mitigation
Publication: Geotechnical Earthquake Engineering and Soil Dynamics V: Liquefaction Triggering, Consequences, and Mitigation (GSP 290)
ABSTRACT
Noting that injection of expanding resin mixtures into the ground has long been used worldwide for the re-levelling of buildings that have suffered foundation deformations, the aim of this study was to examine whether the same process could also be a viable form of ground improvement, primarily for liquefaction mitigation. A controlled field investigation was carried out into the efficacy of this ground improvement technique, in which three test sites were selected for the construction of resin-injected test panels. The pre- and post-improvement soils at all three sites were assessed using a variety of methods. The results of the study show that significant improvements in soil density and stiffness were achieved, thus demonstrating that resin injection is a viable ground improvement method in the right soil conditions.
