b) The soil layers on a site consist of: 0 - 10 m sand (g- 20 kN/m) 10-15 m clay (g 22 kN/m') Draw an effective stress/total stress profile between 0 and 15 m, when the water table is at a depth of 5 m below the ground surface. If because of capillary action the soil becomes fully saturated upto 3 m above the ground water table, what will be the value of total / effective stress at a depth of 3 m below the ground surface? Assume g 22 kN/m' for fully saturated soil.

Transcribed Image Text:b) The soil layers on a site consist of:
0 - 10 m sand (g- 20 kN/m)
10-15 m clay (g 22 kN/m')
Draw an effective stress/total stress profile between 0 and 15 m, when the water table is at a depth of 5 m
below the ground surface. If because of capillary action the soil becomes fully saturated upto 3 m above
the ground water table, what will be the value of total / effective stress at a depth of 3 m below the ground
surface? Assume g 22 kN/m' for fully saturated soil.
Expert Solution
Condition 1: To To draw effective stress profile between 0 and 15 m when water table is below 5 m:
The diagram of soil profile indicating water table can be drawn as:
