Driven pile test programs may include static load testing, which involves incrementally loading a pile while measuring (at a minimum) pile deflection. Static loads may be applied in axial compression (from the top down, or from the bottom up), in axial tension, or laterally. The most-common type of static load test is top-down axial compression. It is worth emphasizing that the main objective of static testing is to characterize soil behavior. In pile design, this is where the majority of uncertainty exists, as pile behavior can be predicted reasonable well. Static compression and tension load test piles may be instrumented to obtain load-transfer information (i.e., shaft resistance distribution) to correlate with static analyses and/or dynamic testing results, characterize set-up, estimate shaft resistance in scour, down force, or liquefiable zones, etc. Static lateral load test piles may be instrumented to obtain deflected-shape information to aid in refining lateral pile design software input parameters.
