enhanced pipe piles are made by centrifugal rotation and steam curing under high temperature

so it is very difficult to embed concrete strain gauges during making piles. A new method is used to embed concrete strain gauges in piles. Based on the static loading tests on enhanced pipe piles

the load transferring mechanism of enhanced pipe piles is studied through analysing axial load distribution

behaviors of skin resistance and base resistance of piles

and load sharing of rims of enhanced pipe piles. Experimental results show that when axial load acts on the top of enhanced pipe piles

the upper rims of enhanced pipe piles act on skin resistance of piles before the lower rims do

and the rims of enhanced pipe piles remarkably reinforce skin resistance of piles.
