Q- How does water affect the behavior of
a. Sandy Soil?
b. Clayey Soil?
Homework Answers
a. Due to presence of water in sandy soil bearing capacity of foundation can decreases because due to water submerged weight of soil is decreases and bearing capacity is decreases.
b In case of clayey soil bearing capacity of foundation is decreases and and chances of consolidation leads to settlement of soil takes places.

The depth of water in a lake is 4 m. The soil at bottom of the lake consists of sandy clay. The water content of soil was determined to be 25.0%. The specific gravity of the soil grains is 2.70. Determine the void ratio and unit weight of the soil. What would be the total stress, effective stress, and pore water pressure at the 5 m depth into the bottom of the lake?...

Problem 4: a) Calculate the total overburden, effective stress and pore pressure distribution for the soil profile below. Neglect the surcharge for this analysis. Draw out all pressure profiles in a neat manner using a ruler. NO sketches and sloppy drawings permitted. b) Calculate the change in pressure if the water table rises to the interface of the clayey/sandy soil layers. You may show your results graphically or report the change in pressures along with the new pressures at the...

17.6 ung Coulomb's earth pressures. It is required to design a cantilever retaining wall to retain a 5.0 m high sandy backfill. The consultant suggests the dimensions and soil properties shown in Figure P17.6 and requires that the wall be checked for stability with respect to sliding and overturning based on the active earth pressures determined using 0.5 mm 110° EDT Sand y = 18.5 kN/m3 6' = 36°...
