    Abstract

    The rate of load application during a Statnamic pile test is beheen that of static and dynamic pile tests. Current analysis methods offer excellent correlation between Statnamic and static test results for coarsened soils. However, over-prediction of pile load capacity can be obtained for fine-grained soils. It is very difficult to explore this anomaly using full scale field tests because of natural soil variability so a study has been carried out using a mode1 pile installed in similar clay beds prepared in a large triaxial calibration chamber. The instrumented model pile has been loaded at varying rates by a computer controlled servo-hydraulic actuator. The tests have simulated static loading, constant rate of penetration at various rates of penetration, and Statnamic loading. Results suggests that components of the rate effect associated with increased pile penetration rates may be described by a power law relationship.
