7.17 A soil profile consists of a clay layer underlain by a sand layer, as shown in Figure P7.17 If a tube is inserted into the bottom sand layer and the water level rises to 1 m above the ground surface, determine the vertical effec- tive stresses and porewater pressures at A, B, and C. If K, is 0.5, determine the lateral effective and lateral total stresses at A, B, and C. What is the value of the pore- water pressure at A to cause the vertical effective stress there to be zero?
