Abstract:

This paper describes research into the physical and chemical property changes that occur in an active clay soil during and shortly after injection witth lime and fly ash slurries. It reports on the changes measured for 20 properties by using 112 samples taken both before and after injection. It describes the design of the experiment, where four treatments were randomly applied in four replications. It describes the property changes noted that were significant and explains how the monitored ground surface elevations changed during the project. The paper describes the processes used for statistical analyses of property changes measured. This description includes two types of analysis of variance and comparison of means before and after treatment. Those properties concluded to have significantly been affected by injection stabilization included water contents, plastic indices, swelling potential, cation exchange capacities, calcium levels in pore water, and calcium levels in the exchange complex. The ground level monitoring analyses presented support the stabilizing effects of lime slurry pressure injection (LSPI). Conclusions include the relative ranking of the treatments applied where a single LSPI followed by a three-staged water injection proved most effective. (Authors)
