Our research group's focus is liquefaction of strong ground, and in particular the liquefaction of mine tailings mixed with binder and called Cemented Paste Backfill (CPB). The very nature of the underground mining environment and the methods used to extract ore result in boundary conditions and imposed static and dynamic loads that are fundamentally different from the near-surface natural soil deposits which have been the focus of traditional liquefaction studies. This provides the impetus to go beyond the traditional areas of liquefaction research and explore exciting new areas including the effects of binder hydration, unsaturated water phases, frequency dependance under sustained high frequency loading, heterogeneous in situ conditions, and also how rheology modifiers influence post-liquefaction behaviour.
