Good Agreement

In this paper, we use two-phase mixture model and the Realizable k-ε turbulence model to numerically simulate the advection secondary flow in a sedimentation tank. The PISO algorithm is used to decouple velocity and pressure. The comparisons between the measured and computed data are in good agreement, which indicates that the model can fully simulate the flow field in a sedimentation tank.

The interface of non-woven geotextile and HDPE geomembrane based on direct shear test has an obvious softening behavior. This paper adopts displacement-softening model that proposed by Esterhuizen and conducts secondary development by using ABAQUS and its embedded FRIC subroutine, making further efforts to conduct numerical simulation of interface of non-woven geotextile and HDPE geomembrane based on large-size direct shear tests. Results show that the developed interface friction model can simulate the characteristics of interface softening of certain materials better, thus providing a method when study the interface softening characteristic of materials.

Pressuremeter Modulus

This paper presents a study of the pressuremeter test and the results that can be obtained from this test. Hostun's fine sand was chosen as the material upon which to perform the experimental study of the pressuremeter. Numerical simulations of the pressuremeter tests have been made with the commercially available PLAXIS software. The numerical results have been compared with the experimental ones. The variation of the parameters resulting from an applied surcharge was studied experimentally and numerically. Finally, the relationship between the magnitude of the deformation and the pressuremeter modulus was analyzed.Key words: sand, pressuremeter, triaxial, pressure, modulus, deformation, numerical simulation.
