Modelling Water-Induced Compaction of the SaalianGlacial till in Lower Lusatia

S. Narra

Abstract:
The objective of this study is to understand the water induced consolidation process at agriculturally used reclaimed soil. The approach of the study is to reproduce the situation occurring when the soil is subjected to water induced compaction at defined loads typical in the top soil (0 to 20 kPa). The water induced compaction process is characterized by sudden change in the voids or pores of the soil that are loaded at their natural water content and flooded. Compression properties are measured with Oedometer tests using sieved sandy loam, taken from a non weathered Saalian glacial till layer, as the meta-stable test soil. Pre-consolidation load calculated for the dry samples overestimated the simulated overburden pressure, whereas, the wetted samples showed a high congruence. In both cases, the point of greatest curvature estimated in the earlier step of deviation gave values that are more realistic to the loads from which the unloading started. The results indicated that both dry compaction and water-induced compaction induce primarily plastic deformation.
