Preconsolidation pressure can be defined as the maximum effective stress that a soil has experienced throughout its life. This pressure is very important in geotechnical engineering because it predicts the rate and amount of settlement behaviour based on laboratory tests using consolidation test data for structuzseres founded on clay.
Two different methods of obtaining the parameters of the preconsolidation pressure and correcting for sample disturbance using Schmertmann’s correction for 200 consolidation tests performed on the soil samples obtained from various transportation projects Benghazi city, and the results that used in this paper were obtained in soil lab in Benghazi University. Pacheco Silva (1970) and Simple Method (Holtz et al. 2011) were investigated in this study. According to the test results, these methods may estimate different values of preconsolidation pressures. Moreover, statistical analysis was studied for these methods by using the Reliability Analysis software with collected data from laboratory tests. The results showed that the preconsolidation pressures for simple method have higher values compared to Silva method
