摘    要:依据上海地区某工程中采用桩底注浆、桩侧注浆和没有注浆的3根试桩的单桩竖向抗压静荷载试验结果,通过对基桩的竖向极限承载力性状、桩身轴力传递特性以及桩侧阻力发挥特性和桩端阻力发挥特性的综合分析研究,揭示了桩底注浆、桩侧注浆对基桩承载性状的影响情况,得出了一些对相同地区同类基桩的设计、施工和深入研究具有指导意义的结论。

关 键 词:钻孔灌注桩  桩底注浆  桩侧注浆  承载性状  比较研究

Abstract:According to the experimental result of vertical static compression capacity of 3 single test pile, a pile grouted from the base, a pile grouted from lateral and a pile without grout, this paper revealed the influence of the way of grouting, from the pile base and the lateral, on the bearing character of pile and the result obtained could guide the design, construction and further investigation on similar foundation pile in the same region.
Keywords:bored filling pile  grouting from base  grouting from lateral  character of beating  comparison study
