Modélisation numérique de la stabilité d’un Barrage en Terre sous PLAXIS 3D.

Abstract

The objective of this study is to calculate the safety factor of a dam using the PLAXIS numerical simulation software. The safety factor is crucial in determining the equilibrium and stability of a dam. The numerical analysis conducted in this study has led to the development of a model that takes into account the geotechnical properties of the soil as well as the fluctuations in the water level. The goal is to evaluate the sensitivity of the safety factor to these parameters. The calculations of the safety factor are based on the finite element method, using the Mohr-Coulomb model. This method allows for the representation of the mechanical properties of the soil, such as cohesion and internal friction angle, and enables the determination of stresses and deformations within the dam structure
