Abstract:
Testing of bored piles is carried out to investigate the load-settlement behavior of the
tested pile. The pile is loaded upto about l.5 times the working load to establish the loadsettlement
behavior. The termination of the load testing at 1.5 times the working load is
mainly due to the cost associated with providing the reaction load required to load the pile.
If the pile doesn't reach the ultimate failure before the final test load, the ultimate carrying
capacity of the pile cannot be obtained directly from static load testing. Therefore, it is not
possible to obtain the Factor of Safety (FoS) of the pile against the shear failure of the soil
surrounding the pile.
