A comparison between the factor of safety calculated by this method and those computed according to Tschebotarioff and Terzaghi (empirical methods) is also included. Chapter 4 contains a parametric study of strutted excavations by the Finite Element Method in which a linear elastic model was used. A comparative study between the factor of safety against the overall (basal) failure by the FEM and by the Bishop’s Simplified Method is included.
