 Summary:
 By examining the soil and the rock mass is one of the main parameters to be determined is the angle of internal friction. Soil friction angle is a shear strength parameter of soils. Its definition is derived from the Mohr-Coulomb failure criterion and it is used to describe the friction shear resistance of soils together with the normal effective stress. In the stress plane of Shear stress-effective normal stress, the soil friction angle is the angle of inclination with respect to the horizontal axis of the MohrCoulomb shear resistance line. This paper presents the values of the angle of internal friction obtained on the basis of research and testing in situ and which are a big help to designers.
