Question

Compute the unit bearing capacity in kips per square foot of a
footing 10 ft2 resting at a depth of 2 ft below the surface of a
coarse sand and subjected to a total load of 400 kips. The water
table is at a depth of 2 ft and the corrected value of NSPT is 30.
The total unit weight of the sand is 122 lb/ft3 . Compute the
factor of safety for the load of 400 kips.

Answer #1

QUESTION 2 A square footing has to be designed using Terzaghi's
bearing capacity equation on a soil with these given parameters:
unit weight =115 lb/ft? effective angle of internal friction = 30°,
effective cohesion = 500 lb/ft, factor of safety = 3. The bottom of
the footing is located at 5 ft below the ground surface. The ground
water table is far below the bottom of the footing and has no
impact on soil bearing capacity. What is the minimum...

Repeat problem 8.2 using Schmertmann’s method, compute the
settlement of this footing att = 50 years. (divide the soil into 6
layers, 3 ft thickness for each layer)
8.2) A 250-k column load is to be supported on a 9 ft square
footing embedded 2 ft below the ground surface. The underlying soil
is a silty sand with an average N60 of 32 and a unit weight of 129
lb/ft3. The groundwater table is at a depth of 35 ft....

Plate load test is adopted globally to determine in-situ bearing
capacity of the subsoil and considered as one of the most important
field test for any big construction project. A plate load test was
conducted on a 300 mm side square plate at a depth of 1.10 m below
the ground level in pure clayey soil for an important construction
site. Failure of the soil occurred at a load of 45 kN. A. Calculate
the safe bearing capacity of a...

A proposed square footing carrying a total load of 2,100 kN is
to be constructed on a uniform dense clean gravel. The gravel’s dry
unit weight is 20.7 kN/m3, and its angle of internal friction is
34°. The depth of the footing is 1.7 m below the ground surface.
Groundwater was not detected during the drilling program. Determine
the minimum dimensions of this proposed footing, using a factor of
safety of 3 and an assumed footing thickness of 0.5 m.
