The soil profile at a site consists of 10 m of gravelly sand underlain by a soft clay layer. The water table lies 1 m below the ground level. The moist and saturated unit weights of the gravelly sand are 17.0 kN/m3 and 20.0 kN/m3, respectively. Due to some ongoing construction work, it is proposed to lower the water table to 3 m below the ground level. What will be the change in the effective stress on top of the soft clay layer?

need fast please A 15-m thick soil has water table 4 m. below the ground surface. The soil has a void ratio of 0.44 and specific gravity of 2.68. Above the water table, the soil has a degree of saturation equal to 49.14%. Direct shear test conducted on the soil shows that the an angle of internal friction of 27.45° and cohesion of 17.89 kPa. What is the potential shear strength (in kPa) on a horizontal plane at a depth of 8 m. below the ground surface? Round off to two decimal places.

Plz give the correct answer. Compute the intensities of active and passive earth pressure at depth of 8 m in dry cohesionless sand with an angle of internal friction of 30 degrees , and unit weight of 18kN / (m ^ 3) What will be the intensities of active and passive pressure if the water level rises to the level? Take the saturated unit weight of sand as 22kN / (m ^ 3) .
None
A soil deposit exists with a level ground surface. The saturated unit weight of the soil is 125 pcf, and the water table is at the ground surface. (a) Determine the principal stresses acting at a depth 15 ft below the ground surface that results from the effective (submerged) soil weight if the lateral pressure is 0.45 times the vertical pressure. (Recall that the subsurface vertical and horizontal pressures or stresses are the principal stresses when the site surface is horizontal.) (b) What is the magnitude of the maximum shear stress relating to the effective stresses at this depth?
Answers a) 0.917 b) 9.17 cm c) 1.08 N
