During testing, hydraulic pressure is applied to the jacks, creating bidirectional forces that push upwards against the pile shaft and downwards against the pile toe. The Bidirectional Static Load Test (BDSLT) is an advanced method of pile load testing used to determine the axial load-bearing capacity of deep foundations (bored piles, drilled shafts, barrettes, etc. Unlike traditional top-down load tests, the BDSLT applies loads both upwards and downwards from. Bi-directional static load testing (BDSLT) for piles is the most economical & reliable method for performing loads test and optimization process. Its major advantage is non-requirement of heavy beams and dead loads for the reaction load. The test load applied was 10,800 tonnes which can usually not be applied by a traditional static load test.
