Table of average values of the angle of internal friction for different soils. Soil internal frict

Internal friction angle - the angle of inclination of the straight part of the diagram shear axis normal to the ground pressures. The angle is a measure steam enthalpy calculator of the internal friction of the friction forces in the soil, resulting in a shift phenomena and provide resistance to shear. Based on their own research and regulatory literature revealed the average value of the angle of internal friction for different soils.

The void ratio is changed from zero (no pores) to infinity (skeleton soil is absent). The lower the porosity, the greater the angle of internal friction.
