How is bidirectional testing of pigtails conducted
The Bidirectional Static Load Test (BDSLT), a self-reaction method, eliminates the requirement for the reaction load needed for the traditional pile loading test in order to solve these issues. Instead of applying load from the pile head, this test uses a. Upon application of load, the pile is separated into two sections and load is applied to both sections simultaneously and reacting against each other in two directions; upward against upper skin friction and downward against base bearing and lower friction. Its major advantage is non-requirement of heavy beams and dead loads for the reaction load.
