Question: Two identical soil specimens were tested in a triaxial apparatus. First specimen was failed at a deviator stress of 700 kN/m2 when the cell pressure was 200 kN/m2. Second specimen was failed at a deviator stress of 1300 kN/m2 when the cell pressure was 400 kN/m2. Determine cohesion of soil and angle of internal friction of soil analytically.
