Plate Load Test:- Procedure, Bearing Capacity, Limitations

The test essentially consists of loading a rigid plate at the foundation level and determining the settlement corresponding to each load increment. The ultimate bearing capacity then takes as the load at which the plate starts sinking at a rapid rate. The bearing plate is squared, of minimum size, 30 cm 2 and the maximum size is 75 cm 2.
