Webslope, are relatively small. The stress state of a two dimensional critical wedge is perturbed by admitting a small lateral shear, which is accommodated (to maintain criticality) by a reduction in the dominant normal compressive stress. Cohesionless cases are further simplified with Taylor se- ries expansions in the topographic slope. Webwhich assumed a sliding wedge loaded by a soil silo. On the basis of Horn’s model [11], Anagnostou and Kovari [2] proposed the classical wedge-prism model to calculate the limit support pressure in the homogeneous stratum.
