INFLUENCE OF LOADING RATE ON PILE CAPACITY IN CLAY.

Overview
abstract
The analysis of laboratory tests and pile load tests confirms that for clays, the faster the rate of loading, the higher the undrained shear strength and the higher the pile capacity. The data shows that the gain in undrained shear strength due to increasing rate of loading increases with increasing water content, plasticity index, liquidity index, overconsolidation ratio but with decreasing undrained shear strength. A simple model is proposed to quantify the rate of loading effects on undrained shear strength. This model is used to develop rate dependent t-z curves and a computer program to predict the response of a pile subjected to a certain rate of vertical loading.
