Most of the available soils in nature are non-homogeneous and can be considered as a homogeneous layer with simplifications. So far, different methods have been presented in order to achieve bearing capacity of these soil types. Stress Characteristic Lines Method, presented by previous researchers, is one of the best numerical methods able to determine the bearing capacity of foundations. The important advantage of this method over the other numerical methods is that it neither requires the customary and troublesome meshing nor uses complex and specific behavioral models of soil, whereas only the stress field is required
at the collapse moment not the strain field, and the computations are performed with higher speed and simplicity. So far, previous researchers have been able to provide programs through this method in order to estimate the bearing capacity of homogeneous soil. However, this is not true in all cases. Layered soils are mostly encountered in practice. The thickness and also cohesion of
layers are the effective parameters in this regard. The present article evaluates the bearing capacity coefficient (
