Practically, the ground condition usually consists of several layers, which have various properties from each other so it is important to have precise understanding about these layers and their behaviour. For this purpose, two different soil layers in biaxial test was analysed. In the single element simulation, it is impossible to generate the shear strain localization in the porous media but we can get numerous useful results. For strain localization analyse, using multi element models is necessary. The numerical simulation shows that the behaviour of each layer is totally different and the friction angle of both layers changed during simulation.
Geocell soil reinforcement method is became one of the common improvement method used in different aspects of geotechnical engineering. The experimental investigation using physical modelling is somehow complicated and needs more financial support especially when using saturated or partially saturated soil. That’s why nowadays, researchers are trying to use updated numerical methods to simulate the soil behaviour considering above conditions. In this paper, Geocell reinforcement method in embankment construction has been studied using Mohr-Coulomb model. The embankment is overlaid on two layers of soil with different moisture content conditions. The first layer beneath the embankment is a five-meter layer of dry soil and the second layer considered fully saturated soil. The results indicate that embankment reinforcement by Geocell has no significant effect on the excess pore water pressure while the settlement and stress distribution beneath the embankment is highly affected.
