PROBLEM #$3(10$ Points$)$:

You have just learned that a hydraulic gradient of $0\mathrm{.}1$ downwards exists at your project

site. Using this information, recalculate the effective stresses from the ground surface to

the bottom of the deepest subsurface test $($i$.$e$.$ a depth of $80$ ft $).$ Plot these effective

stresses with depth. Briefly explain the effect of the downward water seepage on the

effective stress compared to the static conditions.

PROBLEM #$4(20$ Points$)$:

At the same project site, the project plans call for adding $10$ ft of SP$-$SM fill over the entire

site. This fill has a saturated unit weight of $115$ pcf and a moist unit weight of $110$ pcf

after compaction to $98\%$ of D$1557.$ A surface parking lot will eventually be placed on top

of the fill. Calculate and plot the total stresses, pore pressure, and effective stresses to

the bottom of the deepest subsurface test $($i$.$e$.$ a depth of $80$ ft $).$ Use the information

provided in Problem #$1$ for your calculations.
