Anchors in the Stability Analysis

When performing the stability analysis the actual pre-stressed anchor is automatically replaced by corresponding compressive point forces acting at the anchor head.

The soil at the point of the applied force may, however, undergo plastic deformation. One should therefore carefully assess the resulting distribution of plastic strains. Note that the localization of equivalent plastic strain identifies the location of the potential slip surface. Therefore, if the plastic strains at the anchor head become decisive, it is necessary to introduce some modifications of the original input.
