A soil profile consists of 10-m-thick fine sand of effective size 0.15 mm above a very thick layer of clay. Groundwater level is at 3 m below the ground surface. Determine (a) the height of capillary rise, assuming that the equivalent capillary tube diameter is 10% of the effective size (D10) and the sand surface is similar to smooth glass; (b) the unit weight of three soil layers (unsaturated zone, capillary zone, and saturated zone below groundwater level); and (c) plot the distribution vertical total and effective stresses and porewater pressure with depth if the void ratio of the sand is 0.65 and the degree of saturation is 80% in vadose zone (unsaturated zone). Neglect pore air pressure. (Gs = 2.7, g = 9.8 m/s2, gw = 9.8 kN/m3)

Question

A soil profile consists of 10-m-thick fine sand of effective size 0.15 mm above a very thick layer of clay.
Groundwater level is at 3 m below the ground surface. Determine (a) the height of capillary rise, assuming that
the equivalent capillary tube diameter is 10% of the effective size (D10) and the sand surface is similar to smooth glass; (b) the unit weight of three soil layers (unsaturated zone, capillary zone, and saturated zone below
groundwater level); and (c) plot the distribution vertical total and effective stresses and porewater pressure with
depth if the void ratio of the sand is 0.65 and the degree of saturation is 80% in vadose zone (unsaturated zone).
Neglect pore air pressure. (Gs = 2.7, g = 9.8 m/s2, gw = 9.8 kN/m3)
