Problem- For two infinite slopes (one in dry condition and other in submerged condition) in a sand deposit having the angle of shearing resistance 30°, factor of safety was determined as 1.5 (for both slopes). The slope angles would have been..

Situation 1: A triaxial test is conducted on a cohesionless soil. Failure occurs when the deviator (plunger) stress is 360 KPa. The angle of friction of the soil is 28 degrees. Determine the following: The angle that the failure plane makes with the horizontal a.) 61 b.) 59 c.) 63 d.) 57 The confining pressure in KPa a.) 203.4 b.) 215.4 c.) 224.7 d.) 209.6 The shearing stress at failure plane in KPa a.) 152.4 b.)146.6 c.) 158.9 d.) 163.7

A piezocone test was carried out at a site, and the following readings were recorded for the cone resistance q, and sleeve friction f.. Determine the soil present at these depths.
