Numerical simulation of cone penetration tests incorporating drainage effects
Numerical simulation of cone penetration tests incorporating drainage effects
This paper presents results from numerical modelling of cone penetration tests (CPTs) incorporating drainage effects and compares these results with equivalent model scale CPTs conducted in a centrifuge. A coupled large deformation finite element modelling technique, implemented in the commercial software Abaqus/Explicit using the arbitrary Lagrangian-Eulerian method is presented. The study combines the hypoplastic sand model with hydro-mechanical coupling, which enables modelling of the CPT response of both loose and dense sand under a range of drainage conditions. This modelling technique was validated by comparing the numerical results with the drained cone tip resistance profile measured in the CPTs conducted in a centrifuge. Further simulations were carried out for partially drained and undrained conditions to evaluate the effect of the drainage conditions on cone tip resistance in both loose and dense sand. CPT tip resistance profiles and excess pore water pressure distributions were investigated for these analyses. The findings from this study contribute to numerical modelling and interpretation of CPTs performed under partially drained conditions.
