8) A factory building is going to be constructed on a deep sand deposit. The project engineer has already taken samples from the site and applied laboratory tests (drained triaxial tests) to detemine the shear strength parameters of the sand. The unit weight of the sand is 16kN/m3. The void ratio of the sand is 0.5. Specific gravity is 2.65. In the test, the confining pressure is kept constant as 100kPa and the deviator stress increases gradually until 300kPa (at failure). Calculate the friction angle of the sand.
A clay layer of 25 ft thick is overlain with 50 ft thick of sand (Gs = 2.71). The water table is 20 ft below the ground surface. The saturated unit weight of the clay is 141 pcf. The sand below the water table has a unit weight of 128 pcf. The sand above the water table has an average moisture content of 20%.
