A comparison of soil modelling using CPT and DMT a case study

Abstract

A site investigation campaign using cone penetration test (CPT) and dilatometer test (DMT) was carried on medium stiff silty clay, occasionally sand and gravelly site located at Gemlik, Bursa within a case study. Seismic tests (SCPT, SDMT) were also carried out in order to obtain shear wave velocity profile for seismic modeling. Data obtain from CPT, SCPT, DMT and SDMT testings used for subsoil geotechnical modeling. Soil classification, undrained shear strength, su, internal friction angle, f, constrained modulus M, and shear wave velocity, Vs, profiles, obtained using different insitu measurement techniques, are compared for whole site models and between closely located investigation pairs. Soil modeling are also supported with SPT data, laboratory tests and muti-array analysis of surface waves tests (MASW-MAM). As a result, comparison of the models and the experience attained during investigations are presented.
