Abstract

Preconsolidation pressure is a very important parameter, which describes the stress history and affects the behavior of the cohesive soil in geotechnical engineering. Many graphical methods have been suggested by researchers for determining preconsolidation pressure, these methods include, Casagrande, Schmertmann, Butterfield, Janbu, Tavenas, Van Zelst, old method, and Senol and Saglamer method.
For this research, a comparison was studied between a known preconsolidation pressure and that obtained from all graphical methods. The influence of load duration and load ratio on preconsolidation pressure was also studied in this research.
It has been found that, the method of Tavenas gives the best results of preconsolidation values as compared with the results of the other methods.
