【 摘 要 】

Post-grouting is an effective technology to modify the shortcomings of thick bottom slime and shaft mudcake for the slurry bored pile. Construction procedure, parameter selection and strengthening mechanism of post-grouting bored pile had been introduced in this paper. Development of study on physical and mechanical properties of surrounding soil post-grouted was summarized. The bearing capacity behaviour and deformation properties of the pile were also analyzed. It will provide some advice for the research and application of post-grouting bored pile.
