Question

2. The coefficient of lateral earth pressure at rest K is defined as sat K, (o'h/σ,v) where σ"n and σ,v are the effective horizontal and verti- cal normal stresses. For the soil stratum shown, Ko is determined to be 045, the saturated soil density Ysat is 18 kN/m2 and the water table is 2 m below ground surface. 2 m (a) Assuming the soil is saturated to ground surface and there is no seep- age, plot the at-rest (geostatic) σν, σαν σ'v, σ'n and pore pressure u distributions with respect to depth z down to 10 m below ground surface. (b) what would be σ', at 10 m below ground surface when uniform seepage occurs upwards at gradient i 0.75
