Influence of Tensile Cracks
The program makes it possible to account for the influence of tensile cracks that appear on terrain surface and are filled with water h. The only input parameter is the depth of tensile cracks. The effect of cracks is incorporated when calculating normal and shear forces in sections of a slip surface containing cracks - in a section with tensile cracks the shear strength parameters are set to zero (c = 0, φ = 0). Next, a horizontal force F due to the presence water in a tensile crack is introduced in the analysis (see figure):
