Determine the effective stress on a plane oriented 45 degrees from the horizontal, at a point located at 10 meters of depth in a saturated site. The unit weight of the soil is 20 kN/m 3, the unit weight of water is 10 kN/m 3, and the lateral stress coefficient is 0.5. Express your answer in kPa (but only write the numeric value in the text box).

For the soil strata, draw diagrams indicating the total stress, pore pressure and effective stress profiles to the bottom of clay layer. Fine sand has a thickness of 6 m (FST) with saturated unit weight of 18 kN/m2. Clay has a thickness of 8 m with saturated unit weight of 14 kN/m3 The water table is located at depth of 0.7 of fine sand thickness below the ground surface (i.e. depth=0.7*FST). Fine sand will sustain capillarity (suction). Assume the same...
