Pile Load Test:

Static pile load testing is one of the most common methods for testing the actual in-situ capacity of a pile. The test procedure is based on the direct measurement of pile head displacement in response to a physically applied load.

The test procedure is based on the direct measurement of pile head displacement in response to a physically applied load. The test pile is loaded using a calibrated hydraulic jack that applies the test load to the pile by pushing against a beam placed directly over the test pile.

Similarly, cast-in-situ pile capacity matched fairly well with all the considered methods like: BNBC-2015 static bearing capacity, BNBC-2015 SPT, AASHTO-2002 comparing with the CAPWAP capacity. From this study three relations were established. They are CAPWAP capacity=1.15X BNBC 2015 Static capacity (r2=0.81), CAPWAP capacity=1.04X BNBC 2015 SPT capacity (r2=0.89) and CAPWAP capacity=0.91X AASHTO-2002 capacity (r2=0.92). Recommendation and conclusions were also made for piles of Bangladesh.
