Bearing Capacity Calculation
Bearing Capacity Calculation
(OP)
Dear All:
I am wondering how to consider the effect of soft soils (Soils with low 'N' values)in the boring while calculating the bearing capacity using General Bearing Capacity equation. I mean the soft/weak soils are not at footing depth but are present at a depth between 25-40 ft along the profile and the N values spiked later. How do account or reduce bearing capacity for this type of situation.
Thanks
NT

RE: Bearing Capacity Calculation
Generally, I would rough-size the footing based on the strength of the upper layer, then compare the thickness of the upper layer to the width of the footing. If the depth to the soft layer is more than twice the footing width, it may have no effect, but check it using Page 145.
You will need to address settlement separately. Remember that a point in the deep layer may be stressed by more than one footing.
