Problem 4: a) Calculate the total overburden, effective stress and pore pressure distribution for the soil profile below. Neglect the surcharge for this analysis. Draw out all pressure profiles in a neat manner using a ruler. NO sketches and sloppy drawings permitted. b) Calculate the change in pressure if the water table rises to the interface of the clayey/sandy soil layers. You may show your results graphically or report the change in pressures along with the new pressures at the...
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...
