Relationship between the standard penetration test and the pressuremeter test on sandy silty clays: a case study from Denizli

The standard penetration test (SPT) is the in situ test most commonly used to investigate the properties of silt, clay, sand and fine gravel. The Menard pressuremeter test (PMT) can be utilized to obtain the strength and deformation properties of any soil or weak rock. The study investigated the relationship between the corrected SPT blow count (Ncor) and the PMT parameters of elastic modulus (Em) and limit pressure (pL). It is concluded that for the soils tested, Em and pL can be estimated as a function of Ncor values, with r = 0.91 and 0.97, respectively.
