Numerical modelisation of the stability of liner systems under hydraulic conditions from inclined plane tests

The use of geosynthetics liner system in civil applications submitted to water flow enhanced the development of a new apparatus adapted to conduct tilting tests under hydraulic conditions. To simulate partially the field conditions, these tests are realized with all the components of the liner system in dry then in wet conditions. The test results allow evaluation of the friction properties of geosynthetic interfaces, and the tensile forces developed in the geosynthetic layers. A finite elements code is used for an accurate evaluation of the theoretical tensile forces and to emphasize the influence of water flow on the stability of the system.
