Abstract: Based on the static loading tests on pretensioned high-strength concrete (PHC pile) piles and precast square piles with strain gauges mounted in them which are in the same field, the load transfer mechanism of PHC pipe piles is studied through comparing the load-settlement curves, shaft load distribution, the behaviors of skin resistance and base resistance of two types of piles. It reveals that the behaviors of skin resistance and base resistance of PHC pipe piles is the same as those of precast square piles, however, with nearly the same side surface area, under the maximal load, the development of skin resistance and base resistance of them is different—the average skin resistance of PHC pile is 8.1 % less than the one of the precast square piles while the base resistance of PHC pipe piles is at least 24 % more than that of square piles.

Key words: PHC pipe piles, precast square piles, load transfer mechanism, skin resistance, base resistance
