The pile-base post-grouting technology can solve the bottom slime and the shaft mud-cake which are the two principal deterioration factors of slurry bored piles. The enhancement effect of pile-base post-grouting was analyzed through the comparison static loading tests and summarization of literature data. The hysteretic nature of the enhancement effect was revealed and the abnormal phenomena was analyzed that the initial loading stiffness of deep pile with post-grouting was lower compared with the pile without post-grouting. The settlement-reducing effect of post-grouting is limited at serviceability limit states and the additional settlement effect of end resistance enhancement of pile with post-grouting is proposed.
