Question
Calculate:
a.) The unit weight of soil at a depth of 3m below the ground surface.
b.) The normal stress of soil at a depth of 3m below the ground surface.
c.) The potential shear strength of the soil at a depth of 3m below the ground surface when the water table is at a depth of 3.5m and the soil is cohesionless.
d.) The modified value of the shear strength if the water table reaches the ground surface.
e.) The modified value of the shear strength if the water table reaches the ground surface but the soil has a cohesion of 12 kPa.
Transcribed Image Text:The following are the properties of soil below the ground surface.
Degree of saturation = 50%
