Preconsolidation Stress of Residual Soils in North-central Nigeria

Abstract

Preconsolidation stress of residual overburden soil in North-central Nigeria was studied with depth variation. The results indicate variability of maximum stress on the undisturbed deposit which it has experienced in its geologic past. While at some location, the preconsolidation pressure increased with depth at some other points, the pressure decreased with depth of the residual soils. The observed trend in variability of the preconsolidation pressure conformed with other studies carried out on similar residual profile from other regions.
