In order to quantify the P- and S-wave velocities, dynamic elastic moduli bearing capacity of shallow alluvial sediments, seismic refraction cone penetration test (CPTu) soundings were carr...

A computer simulation of cone penetration in layered soil was carried out using axisymmetric finite element (FE) to investigate soil deformation and soil hardpan prediction during cone penetration. The FE analysis was performed in ABAQUS, commercially available FE package. Soil was considered as a non­ linear elastic plastic material modeled using Drucker Prager material model with hardening op...

Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...

series of undrained monotonic triaxial tests and cone penetration tests were conducted on loose silty sand samples to study correlation between undrained shear strength of silty sands (sus) and piezocone test results. cpt tests were conducted at 27 silty sand samples in calibration chamber. the results indicate that, in low percent of silt (0-30%), as the silt content increases, the undrained s...
