Bi-Directional Load Testing with GRL-Cell

Bi-Directional Load Testing with GRL-Cell Bi-Directional Load Testing is a high capacity static load test method for drilled shafts, bored piles, barrettes and ACIP/ CFA piles.

 

As the GRL-Cell is pressurized, it loads the foundation element in two directions. The portion of the foundation element above the cell location is pushed upward against its shaft resistance, and the portion of the foundation element below the cell location is pushed downward against the toe bearing or “base resistance” and against any shaft resistance below the cell. Shaft and toe movements, as well as embedded strain gage instrumentation, are monitored for each applied load. An equivalent top load movement curve is constructed from the measured shaft resistance load-movement and base resistance load-movement responses.
