Abstract

There remains considerable uncertainty with respect to the cyclic performance of drilled and grouted piles founded in soft calcareous rock. Static and cyclic load testing of three test barrettes founded in a weak carbonate siltstone has been carried out using Osterberg cells. The load test results indicate the shaft resistance performance depends on load and displacement history, and that loss of shaft resistance performance under load reversal may not occur unless the ultimate shaft resistance is achieved during load cycling.
