The ground water table is at a depth of 50 m. Compute the load carrying capacity of the soil
You may use following empirical formula to calculate a (for calculating frictional resistance)
C, - 25kPa
a = 1.0 – 0.5
for 25 kPa < Cu <75 kPa and
50kPa
a = 0.5 for Cu > 75 kPa
Use factor of safety, FS = 2.5
