A small liquid-storage tank is located at the surface of the soil profile shown in the sketch below. The preconsolidation pressure in the clay stratum is found to be approximately 300 psf in excess of the overburden pressure at all depths. Determine the magnitude of the consolidation settlement of the clay after 5 years, for the following situations: (a) Assuming both sand and gravel strata are drainage layers. (b) Assuming only the top sand and gravel layer is drained. 10' Note: Weight of tank itself may be ignored. Liquid stored in tank y = 62.4 pcf 20 -Flexible steel plate 5' GWT Sand and gravel ym. = 110 pcf 25' Medium soft Blue Clay Ysat = 120 pcf 11 C = 0.40, C, = 0.03 c, = 0.01 ft2/day = 42% W= Sand and Gravel
