Q2. Assume a rigid strip footing is constructedon a normally consolidated clay layer under a uniformly distributedvertical load. The depth of footing is zero and the water table isa few metres below the surface ground. The average shear strengthparameters of the clay layer are:
- At the beginning of loading: fu = 0, cu =50 kPa
- Long time after loading:, f’ = 25° and c’ = 0 kPa
Will the bearing capacity of this footing change, if the watertable rises to the ground surface? Briefly explain.
Note: No calculation is required. Assume the ground and thebase of footing are horizontal.
