| Abstract: | The article briefs the application of post pressure grouting to bored pile by describing the strengthening mechanism of pressure grouting to the resistance at pile side and pile end and by presenting quality-control essentials of post pressure grouting. Engineering practice indicates that post pressure grouting can marginally increase the ultimate bearing capacity and effectively lessen settlement of the bored pile. |

| Keywords: | post pressure grouting strengthening mechanism ultimate bearing capacity per pile |
