Abstract
Sliding of a moving soil mass along a basal surface is analyzed and viscous-type sliding laws are presented. They relate the relative sliding velocity at the base—or at an interface—to the state of stress at this surface. Examples of practical parameter determination illustrate the suitability of this approach; two landslides (in Switzerland and in France) provide the data for this purpose. A third site (La Frasse, Switzerland) serves as an example of three-dimensional analysis of creeping slopes using the proposed formulation. Comparison of computed and measured velocity distributions shows the method to be promising. Key words: landslides, creep, sliding law, time dependence, interface.Keywords
