Abstract：
Based on the large-scale field test, the accumulation load methods adopted to study the influence of different post-grouted methods (post-tip-grouting, post-side-grouting, tip and side post-grouting) on settlement of pile top. The field tests show that the post-grouted method could decrease the settlement effectively. Compared with the non-grouted pile M1, the settlement of post-tip-grouted pile M2 decreases 0.86 mm; the settlement of post-side-grouted pile M3 decreases 1.32 mm; the settlement of tip and side post-grouted pile M4 decreases 1.42 mm. After adopting post-grouting, the loading-settlement curves are similar to lines, the limited loading of which will increase dramatically.
