Using CPT and CPTu Results for Determination of Soil Shear Strength Parameters Consideration with 16 Practical Cases

The most common method for determining soil shear strength parameters is using laboratory tests and Mohr-Coulomb criteria. These methods have some limitations such as preparation of undisturbed samples, samples size, modeling of real in-situ stresses in laboratory condition, discontinuity of data. According to the repeatability and continuous measurements in CPT and CPTu, these tests results used for determination of soil strength parameters in geotechnical engineering. Most studies in fine soils focused on determination of undrained shear strength while in geotechnical design long-term bearing capacity is considered. Thus, in this paper a new method has been suggested for determination of c and
