摘要：

The use of geosynthetic lining systems (GLS) is increasingly widespread in hydraulic civil engineering structures. Studying their stability generally requires calculating their friction angle materials. This is carried out using a shear box or an inclined plane, the latter being more appropriate for the cases of low normal stress. The design and construction of an inclined plane that respects the existing standards is described. The test also enables under hydraulic conditions to study the influence of water on GLS stability. A large number of interfaces were tested in dry and wet conditions, these tests enabled us to verify the influence of water on GLS stability. An in situ experiment was carried out with the aim of validating the inclined plane tests. Finally, on the basis of the experiment result, stability calculations for an example are presented. These highlight the need to take the effect of water into account when designing such systems. (C) 2002 Elsevier Science Ltd. All rights reserved.
