Abstract: Base on the static loading tests on prestressed high-strength concrete piles with strain gauges at the top and toe of pile and at interfaces of soil layer, the load transfer mechanism of PHC piles was studied; and the behaviors of skin resistance and inner force were analyzed. Based on the static load test on prestressed high-strength concrete piles (PHC piles) of a practical engineering, using the elastoplastic model, nonlinear interface elements and nonlinear soil elements, by the finite element method, pile-soil interaction of PHC pile in the soft soil area were simulated. The results of analysis indicate that there are many differences between the numerical predictions and the experimental results; however, it shows that the calculated distribution trend is in good agreement with the experimental results.

Key words: PHC piles, finite element method, load transfer mechanism, skin resistance
