Infinite Slope

In case infinite slopes failure takes place due to the sliding of soil mass along a plane parallel to the slope at a certain depth and this type of failure is referred as translational slides. Figure 28.2 shows the forces acting on an element in the infinite slope. The soil is assumed to be homogeneous. In the Figure 28.2, W is the weight of the element. From the figure it is written as:

\[W=\gamma \,zb\cos \beta\]                       (28.1)

\[{\sigma _n}={{W\cos \beta } \over b}=\gamma \,z{\cos ^2}\beta\]                          (28.2)

\[\tau={{W\sin \beta } \over b}=\gamma \,z\cos \beta \sin \beta\]                                 (29.3)

where σn is the normal stress, t is the shear stress and \[\gamma\] is the unit weight of the soil.
