摘要：The assumption of an associated flow rule overestimates the volume increa during shear than that is obrved for most of the soils and also for an associated flow rule the stress acting over various rupture surfaces do not appear in the energy rate expressions. For a non-associated non-coaxial flow rule it is esntial to define the stress along the rupture surface to find the rate of dissipation of internal energy. In the prent work, stability number for the homogeneous soil slope obe互联网知识

ying non-associated non-coaxial flow rule has been determined by defining the stress along the rupture surface using the assumption of interslice forces as earlier introduced by Fellenius (1936) and Bishop (1955). In the analysis, effects of ismic force have been also incorporated. Optimization methods and neural network have been
