THE BEHAVIOR OF AN AXIALLY LOADED DRILLED SHAFT UNDER SUSTAINED LOADING

This study pertains to the possible deleterious effects of sustained loading on the capacity of a drilled shaft. Long-term phenomena of creep and consolidation are considered. From a literary research it was found that creep can have the eventual effect of load shedding, a transfer of load to the lower regions of the shaft. This phenomenon, it is believed, can have the effect of increasing settlement. From field observations and measurements taken during the course of loading, it was found that little load shedding had occurred. It is believed that this is a result of the relatively low stress levels in the soil compared to its capacity.
