Test: Pile Load

The pile load test can be performed on a working pile which forms the foundation of the structure or on a test pile.

For the pile in cohesive soil, point bearing is generally neglected for individual pile action, since it is negligible as compared to frictional resistance.

The separation of Q at any stage of loading into Rp and Rf in cyclic test is based on experimental found value of A.F. Van Weele (1957) that the load on the pile toes (1957) that the load on the pile toe (i.e. RP) increases linearly with the elastic compression of the soil.

The result of Dutch cone penetration test can be applied with sufficient accuracy to determine the ultimate bearing capacity of piles in cohesion soils.

The IS code recommends that for working out allowable load, a minimum factor of safety 2.5 or 3 should be used.
