WebbAn additional optional module offers further methods of analysis; piezometric grid definition and the ability to analyse non-circular slip surfaces. A further optional module adds the ability to analyse reinforced soil including the use of tie back wedge analysis and two part wedge analysis. WebbDetails of the "tie back wedge" method is described BS8006. In the document HA64/98, the limit equilibrium approach is also adopted for designing reinforcement of steep slopes. It also incorporates partial factors and the design is based on a two-part wedge mechanism which is preferred because it provides a harbour towne health muskegon mi
