Abstract: The strength of the wet deep mixing (DM) improved soil has been found to be often highly variable and has been attributed to the non-uniformity of mixing. However, various factors that affect the non-uniformity of mixing are not clearly understood. The aims of this study were to assess the feasibility of studying DM processes by using centrifuge modelling and to examine various factors that affect the uniformity of mixing. Scaling relationships which are essential in centrifuge modelling DM process in a reduced-scale centrifuge environment were first examined. A series of parametric studies were then conducted. Results obtained from centrifuge parametric studies showed that lowering the viscosity of the binder, increasing the work done in mixing and adjusting the density of the binder so as to minimize density differences between soil and binder can all contribute to minimizing the variation in the binder distribution and thus improving the uniformity of mixing.
