Question
The soil profile at a site consists of 2 m of clay (ybulk = 19.5 kN/m3; y sat
20.93 kN/m3) overlying a deep deposit of gravel (ybulk = 16.8 kN/m3; ysat
= 17.41 kN/m3). If the water table is at the top of the clay, determine the
depth from ground surface at which the effective vertical stress is 120
kPa(also from the ground surface). Assume the unit weight of water is 9.81
kN/m3.
