41. 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
42.
43. 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
44. 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)
