| 摘 要： | 文章从改善桩本身性能、改善土层性能、加强桩土相互作用等三个方面对后压浆法提高灌注桩的承载力的作用机理进行了分析.在上述分析的基础上,结合土层情况和Q-s曲线类型对桩端注浆或桩侧注浆方法的选取进行了总结.最后,讨论了桩型、土质条件、压浆量和注浆压力等因素对于后压浆法效果的影响.

| Abstract: | The mechanism,i.e.,using mud-jack method to increase the bearing capacity of driven cast-in-place pile,is analyzed in the paper from three aspects:meliorating performance of the pile,improving performance of soil layer and reinforcing the interaction of pile and soil.Based on the above analysis,combined with the actual condition of soil layer and the type of Q-S curve,applicability of pile-end-grouting method and pile-side-grouting method are summarized.And finally effects of mud-jack method caused by pile types,soil conditions,grout amount and grouting pressure are discussed. |

| Keywords: | driven cast-in-place pile mud-jack method bearing capacity of pile effect of grouting |
