Based on the Bao Mao Highway Guangdong Section of a Soft reach 40 m high embankment reinforcement of PHC pile sections of field experiments, the study of PHC pile bearing capacity growth law in the construction period. The results show that when the filling height of less than 30 m, bearing capacity of piles and fill height was a good linear relationship, when the filling height is greater than 30 m, test pile surrounding soil will produce a downward displacement of the opposite pile, so that the pile of negative friction resistance of soil to pile carrier transfer that pile bearing capacity increased filling height increases faster.
