Question: PLS HELP A - G ! ! A soil profile consists of 8 meters of compacted sandy loam followed by 1 6 meters of alluvial

PLS HELP A-G!!
A soil profile consists of 8 meters of compacted sandy loam followed by 16 meters of alluvial dense sands. Below the alluvial sand is a layer of compressible fat clay (CH) that is 24 meters thick. The initial groundwater table is located at the bottom of the first layer (depth of 8 meters). The total density of the compacted sandy loam is 2.08Mgm3( total). The total (saturated) density of the alluvial dense sand is 1.92Mgm3( sat). The total (saturated) density of the compressible fat clay is 2.78Mgm3( sat). The Ko of the compressible fat clay layer is 0.7. The Ko of the sandy loam and alluvial dense sand layers are 0.5. You may assume that no capillary rise exists for all questions.
a. What would the total vertical stress (in units of kPa ) be at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
b. What would the pore water pressure (in units of kPa ) be at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
c. What would the effective vertical stress (in units of kPa ) be at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
d. What would the effective horizontal stress (in units of kPa ) be at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
e. What would the total horizontal stress (in units of kPa ) be at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
f. How would you expect that the effective vertical stresses at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters) would change if the water table were to rise (above a depth of 8 meters) after a heavy rainfall? Select the best option.
a) Effective vertical stresses would likely increase
b) Effective vertical stresses would likely decrease
c) Effective vertical stresses would likely stay the same
d) Effective vertical stresses might increase or decrease depending on K0
g. Imagine that a dewatering operation was used to drop the groundwater table from a depth of 8 meters down an additional 16 meters to the top of the compressible fat clay (CH layer (depth of 24 meters). Assuming that total unit weights do not change, what would the new effective vertical stress be (in units of kPa ) at a point at mid-depth in the compressible fat clay (CH) layer (depth of 36 meters)?
