In this paper CPT data has been used for evaluation of soil stiffness (E). The CPTu records are continuous and accurate in soft soils which suffer settlement problems. In 1967, Janbu presented a relation to determine the settlement for cohesive and non-cohesive soils, regarding a stress-strain approach, based on two parameters that are called (m) and (j); modulus number and stress component, respectively. In this study, it has been attempted to correct the m and j parameters using CPT data in the form of soil behavior classification charts. A data bank has been compiled containing fifty two practical case histories, including shallow foundation full scale load tests and CPT performed close to them. The results of validation indicate that the proposed approach is able to predict the settlement close to their real values and its accuracy is more than other common methods, such as Janbu, Meyerhof and Schmertmann methods.
