Preconsolidation Pressure Predicted Using /¯ Ratio

Source

This paper illustrates the use of Skempton's sup relationship along with the undrained shear strength for predicting the preconsolidation pressure for lightly overconsolidated clays. The validity of this prediction procedure is demonstrated by test results on soils from the Chicago area. A good correlation was found between predicted versus measured preconsolidation pressure. The relationship between liquidity index and measured preconsolidation pressure was also evaluated and found to be rather poor for the Chicago area soils studied.
