SHEAR STRENGTH OF SOILS

Shear strength of soil Soil cannot resist tension Soil can resist compression. For excessive compression failure occurs in the form
of shearing along the internal surface within the soil Structural Strength of soil = f ( soils shear strength) Shear Strength Soils ability to resist sliding Important for foundation design Lateral earth pressure calculations Slope stability analysis
