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 ...
