Analysis on Bearing Behavior of Pile With Post-grouted

Bored pile with post-grouted can increase bearing capacity, reduce deformation and enhance the quality of pile. In this study, static load tests on four bored piles with post-grouted and one pile without post-grouted were conducted at one construction site. By analyzing Load-settlement curves, axis force distribution of pile shaft, load of pile top and pile end, settlement of pile top over elastic compression of pile, Variation and some factors affected on load transfer of pile-soil system were discussed. This study shows bearing behavior of pile with post-grouted, which have some significance for the design of bored pile.
