Immediate and Long-Term Behavior of the Evanston Tunnel in Chicago Clay
The principal conclusions of this research are: undrained loading during tunneling in clay, non-radial pattern of the immediate displacement vectors, consolidation around the tunnel predominantly in the vertical direction, and long term groundwater infiltration toward the tunnel under constant …

A finite element analysis of the pullout capacity of suction caissons in clay
… suction forces can be relied upon for short-term loading, while the behaviour of the soil remains undrained, but are more questionable for the sustained loading induced by storms and loop currents. This study uses finite element analysis to investigate the uplift capacity of suction caissons under …

A THREE-DIMENSIONAL FULLY COUPLED HYDRO-MECHANICAL ELASTO-PLASTIC MODEL FOR UNSATURATED SOILS WITH CONSIDERATION OF HYSTERESIS BEHAVIOR
… in which it is subjected to cyclic traffic loadings and/or seasonal wetting-drying cycles. While mechanical hysteresis is a common feature of soils in general, hydraulic hysteresis is associated with unsaturated soils. Most existing constitutive models paid limited attention to the …

Cyclic behavior of cohesionless granular media using the compact state concept
… of sands under monotonic and cyclic, drained and undrained loading conditions. The numerical results indicate that samples looser than the critical void ratio have a very high potential to collapse upon loading. Deposits denser than the critical void ratio could also liquefy as the tendency to …

Modelling the effect of recent stress history on the deformation of overconsolidated soils
… response of the soil for the current loading path. The data from the tests together with a re-evaluation of the existing experimental data and a limited investigation of the effect of recent stress history in 3D stress space, enabled the main features of the soil behaviour to be …

Shear behaviour and stiffness of naturally cemented sands
… the soils were sheared after isotropic yielding. Undrained loading-unloading probes showed that the linear behaviour was reversible and that plastic strains were accompanied by a progressive deterioration of bonding resulting initially in a reduction of the yield stresses and finally, after …
