Abstract
AbstractThe piezocone penetration test (CPT) and flat dilatometer test (DMT) are routinely used in geotechnical practice and are often considered adequate for detailing of soil profile and determination of soil properties. This paper presents comparison of results of ground characterization and evaluation of soil properties based on the combined use of CPT and DMT at four different locations, each with different ground composition. Evaluation of both tests in terms of soil type, undrained shear strength, constrained modulus and friction angle is presented and results are compared. In some cases the results are also compared with laboratory data. The main objective is to show that companion sets of CPT and DMT at a given site could be used to better define the geotechnical ground model and to increase confidence in the evaluation of soil properties.
