摘　　要：针对某桩筏基础工程中,单桩竖向抗压承载力不满足设计要求且桩身存在缺陷的问题,提出了微型灌注桩加固方案,通过估算缺陷桩的承载力值,确定了单桩承载力设计值,满足了加固设计的要求。According to the problems that the single pile’s vertical compressive loading capacity can not meet the design demands in some pile raft foundation projects and some defects in its pile,the paper points out the mini-bored pile’s consolidation scheme,and identifies the design value for the single pile loading capacity according to the estimation of the loading capacity of the defective piles,so as to meet the demands of the consolidation design.

关 键 词：灌注桩 单桩承载力 桩基加固 桩筏基础
