| Abstract: | In the recent years,as a new technical measure for increasing the bearing capacity of bored piles,the base grouting of the piles has been popularized and applied to bridge construction.In this paper,the changes of the indices of soil behavior at the bases of bored piles before and after the bases are grouted are studied and analyzed through tests,and the functions and effect of the grouting at the bases are also analyzed from the angle of mechanism of the grouting. |
