摘要: 本文对浙江上塘河桥工程的钻孔灌注桩未注浆桩和注浆桩载荷实验对比分析,并通过与单桩载荷对比分析,确定有限元ANSYS的模型参数,以此单桩的ANSYS有限元模型,分别对未注浆桩、注浆桩的注浆体尺寸不同情况下承载力大小的对比分析,并得出关于钻孔灌注桩桩端后注浆承载力的提高实质是破坏模式的转变。

Abstract: This paper on the zhejiang shangtang bridge engineering of the cast-in-place pile static load tests and grouting pile load the contrast analysis,And through the and single pile load contrast analysis, finite element model parameters determined ANSYS, For grouting pile, respectively not grouting pile of grouting body size under different conditions of the size of the bearing capacity of the comparison and analysis, And that bored perfusion pile on the bearing capacity of the essence improve after grouting is the transformation of the failure mode.

Key words: Bored pile, grouting, Module, Bearing capacity
