Abstract

Slope stability with regard of the stress-strain behaviour during shearing. The state of equilibrium of a slope is often evaluated with help of limit equilibrium methods. Here, it is neglected that a deformation in the shear zone has to take place before the maximum shear resistance is reached. The shear stress development depends amongst others on soil density and hydraulic conditions. Consequently, the mobilization of the shear resistance in the shear zone is not homogeneous, which can lead to an overestimation of the slope stability. This report shows a calculation method which couples the development of the slope stability with shear strain in the shear zone. For illustration purposes, two simple examples of a slope with a planar slip surface are shown.
