many tests methods have been used over the years to test the pile
In Tension Pile method a reaction frame is constructed around the test pile
the frame is anchored to reaction(Tension) piles
pile is incrementally loaded with an hydraulic jack
the test load is measured by a Load Gauge
deformation is measured with dial gauges, and surveying instruments
apply load in 10 to 15% increments, maintaining a 30 minute interval
check deformation readings immediately before and after applying load
incrementally increase load until reaching 200% of the design load
remove the load in 4 equal decrements
plot the load-settlement data the point where the load-settlement
curve crosses the failure criterion is the failure load (Qf)
