Question

A 6m thick soft clay layer is overlaying 8 m thick silt layer and with almost impervious thin layer of extremely low permeability between these two layers. The stratum at the bottom of these soil layers (at 14 m depth) is highly pervious silty sand. Water table is at the ground surface (on top of soft clay layer). Determine the required time for 50% consolidation due to compression of the two soil layers when the ground surface is subjected to a uniform surcharge of 80 kpa. The properties of two soil layers are given below. Sp. Gravity coef. Of consolidation void ratio, e0 cc cs ocr soft clay 2.72 0.8 cm2/min 0.94 0.5 0.08 1 silt 2.66 3.6 cm2/min 0.72 0.24 0.05 4
