| Abstract: | This paper presents the numerical simulation of a creeping slope in Upper Austria, using a visco-hypoplastic material law
which describes the mechanical behavior of cohesive soils allowing for viscous effects, i.e. creep and relaxation. The method
consists of: (1) determination of the parameters of the material law, based on laboratory tests on soil samples taken from
the slope; (2) simulation of the laboratory tests with an element test program in which the used material law was implemented,
in order to test whether the model holds for the soils studied; and (3) simulation of slope movements at different sections
along the slope, assuming an infinite slope. The simulation results fit well with the field measurements. This demonstrates
that despite strongly simplified boundary conditions and limited availability of subsurface data (e.g. density) the visco-hypoplastic
law is a promising tool for predicting creep movements. |
