Measurement and prediction of the load distribution and performance of continuous auger piles

Strain gauge data from instrumented pile load tests are often confusing and difficult to interpret. This thesis examines a number strain gauge analysis techniques that are employed to infer axial load distributions in piles. These techniques are then applied to several full scale load tests conducted on bored piles. It was found that applying multiple analysis techniques can help build confidence in the interpretation of load distribution. Using these analyses, the interpreted shaft friction responses are compared with existing practice and suggested parameters in settlement prediction software, such as RATZ. Recommendations are made that assist practitioners in the evaluation of the capacity and load displacement response of bored piles in sand.
