Cone penetration in brittle, lightly over-consolidated soils: a numerical perspective
Cone penetration in brittle, lightly over-consolidated soils: a numerical perspective
The thorough characterization of geomaterials that may potentially liquefy is important, as these materials give little warning of the impending failure, and the consequences of failure are generally momentous. The characterization is generally performed using in situ tests, the interpretation of which has still some degree of uncertainty.
In this work, cone penetration testing is simulated in potentially liquefiable soils using the Geotechnical Particle Finite Element method, specially designed for the simulation of penetration problems in geomechanics. The material response is modelled with CASM, a critical state, state parameter dependent model. This work reports a parametric analysis of cone testing in undrained liquefiable geomaterials. The parametric analysis covers the effect of brittleness and over-consolidation ratio of the geomaterial in addition to the friction angle of the soil-cone interface.
