| Abstract: | In this articel,the author introduces the working procedure and the reinforcing mechanism of the post-grouting technology.According to the data of static loading test for three over-longs bored piles of a project,the author compare the settlement,the axial force distribution along pile shaft and the side resistance of each pile.Base on this analyzed,the noticeable effects on bored cast-in-site piles of the post-grouting technology are reflect veritably and effectively. |
