I am trying to model a geosynthetic reinforced soil structure with segmental blocks facing in PLAXIS 2D. The blocks are modeled with the linear elastic model (specific weight equal to 21.8kN / m³; Poisson's coefficient equal to 0.15 and E = 100MPa) and the interfaces with the Mohr-Coulomb model (interface friction angle equal to 37 °, adhesion equal to 1kPa and Rinter = 1.0). The facing is free to move in all directions. However, the simulations are slow, the displacements increase with constant Mstage and I cannot reach a load of 200 kPa.
Could anyone suggest some parameters that I can change and solve the problem?
Check soil parameters such as modulus of elasticity, angle of internal friction and cohesion, care should be taken with a high friction angle and the cohesion should be at least greater than 0.25 kN/m2
Dear Bianca Alenca,
I think some of your problems maybe related to some stages of process of construction GRS mass for each layer GRS from bottom to top in your mode is not correct. You can be referred in this thesis at pp. 282.
