| Abstract: | Post grouting technique is widely used in resent years. Drill-hole-grouting piling can largely reduce subsidence and lead to homogeneous subsidence. This paper introduces mechanism of raising the bearing capacity by post grouting and some project examples to which post grouting technique is applied and compares vertical bearing capacity limit before and after the grouting then analyses factors that influence the vertical bearing capacity limit. |
