FEniCS simulation of artesian conditions in clay slope

Other conference contribution, 2024

This paper presents a numerical simulation of the response of a slope with ar-
tesian conditions under the impact of a long heavy rainfall event. Sensitivity
analysis of surface and bedrock inclination are presented. The robust FEniCS
finite element tool is used to solve the governing coupled Hydro-Mechanical
(HM) balance equations. An extended version of the Mohr-Coulomb model is
implemented in Fortran and used as soil model. The paper discusses how the
stability is influenced by changes in pore water pressure and the occurrence of
artesian conditions, exploring slopes with different bedrock inclinations. It also
presents potential failure surfaces as part of the discussion. The results provide
better understanding of critical geological conditions, which helps to identify
regions most at risk and take the required safety measures.
