摘　　要：工程中对钻孔灌注桩桩端注浆处理后的桩基承载力的确定往往是做单桩竖向承载力的静载荷实验,得到的实验结果是单桩竖向承载力,但在设计时由于单桩承载力不足而往往是按照注浆群桩进行设计,而注浆群桩和注浆单桩的承载的受力机理是有所不同。本文通过ANSYS有限元软件分析不同桩端土模量、不同桩间距大小和不同浆泡尺寸对注浆群桩的承载力的影响进行分析。To determine the engineering pile after grouting pile bearing capacity is often static load experiment of vertical bearing capacity of single pile, the experimental results obtained are vertical bearing capacity of single pile in the design, but because of the lack of bearing capacity of single pile and is often designed according to grouting pile group, and grouting pile group and grouting pile bearing force mechanism is different. In this paper, the ANSYS finite element analysis software of different pile end soil modulus, pile spacing and different slurry bubble size on the bearing capacity of grouting pile group to analyze the effects of the.
