Choose the correct answer
A
decreasing footing depth
B
increasing footing width
C
decreasing soil-grain compressibility
D
increasing relative density of the sand
Correct Answer
A. decreasing footing depth
Why is this the answer?
General shear failure is associated with dense sands and shallow depths. As the depth of the footing increases, the failure mode tends to shift from general shear to local or punching shear. Therefore, decreasing the depth increases the likelihood of general shear failure, while increasing the depth decreases it.
