Transcribed Image Text:

Consider the soil profile shown in Figure E3-2. The moist unit weight of the top sand layer is 20.0 kN/m. Capillary rise is present above the groundwater table. The saturated unit weights of clay 1 and clay 2 are 17.8 and 18.5 kN/m, respectively. Between these two clay layers is a sand seam of negligible thickness. The tip of Piezometer 1 is within this Sand seam. The tip of Piezometer 2 is at the bottom of the Clay 2 layer. At Points A, B, C, D, E, and F, determine: (a) the vertical total stress (b) the pore fluid pressure (c) the vertical effective stress T 3.0 m 5.0 m 4.0 m Ground surface Sand seam Sand B Clay 1 2.5 m 2.0 m Clay 2 E Sand Figure E3-2 7.5 m Piezometer 1 9.5 m Piezometer 2 Consider the soil profile shown in Figure E3-2.
