Bearing capacity problem example 4

If the water table in Ex. 1  occupies any of the positions (a) 1.25 m below ground level or (b) 1.25 m below the base level of the foundation, what will be the net safe bearing pressure?
Assume ysat = 18.5 kN/m3, /(above WT) = 17.5 kN/m3. All the other data remain the same as
given in Ex. 1
Solution
Method 1—By making use of reduction factors Rwl and Rw2 and using Eqs. (12.20) and (12.23), we may write
