Estimating Internal Friction Angle of Soil Using Standard Penetration Test Data (A Case Study in Babolsar

One of the important parameters considered as a typical characteristic for reconnaissance of granular soils is the internal friction angle. Nowadays, the advances and developments taken place in the equipments of in-situ tests such as those of the standard penetration test (SPT) have facilitated the determination of strength parameters at the site. On the other hand, the existing empirical correlations based on logical argumentations which are provided for estimation of internal friction angle of soils and the standard penetration test, have resolved the problems of experts within the field of construction. Therefore, in this research it is tried to provide a proper correlation between internal friction angle and the corrected SPT blow count for sandy soils of Babolsar based on the results of nearly 46 standard penetration tests and the direct shear tests at the corresponding depths.
