How to calculate angle of internal friction
Did you know?
WebFor the case where the angle of shearing resistance is not equal to zero the situation is not as straightforward as described above because of the necessity to determine the frictional component of the resisting shear stresses. For this case the forces acting on the block are shown in the lower part of Fig. 11.3. WebThe present study focused to estimate the angle of internal friction (ɸ) of cohesionless soil and cohesive (c-ɸ) soil considering field standard pene-tration test (SPT) data. Based on the SPT data an empirical correlation has been established between standard penetration number N and internal friction angle to predict the friction angle of soils.
