  1. A layer of soil consists of 3m thick of moderately dense sand having water content of 40% and specific gravity of 2.81 which in turn underlain by dense clay with water content of 56% and a specific gravity of 1.65. The groundwater table is at the ground surface.

    1. Sketch this scenario

    2. Obtain an expressive for determining the in-situ vertical stress at a point 5m

      below the ground surface.

    3. Determine the effective unit weight of each soil strata (NB: refer from phase relation) AN,5

4.. Determine the effective in-situ vertical stress at the 5m depth

A pipe is driven down through a 5m layer of clay (γ = 17 kN/m3) to an underlying permeable layer. After removing the soil from the pipe, the water level in the pipe eventually rises to 2m above ground level. Calculate the pore water pressure in the clay layer at a depth of 3m below ground level. If the area now becomes flooded to a depth of 1m, what is the pore water pressure in the clay layer at a...
