摘　　要：根据某工程对桩底注浆和未注浆的两根试桩自平衡法静载试验结果,通过对基桩的竖向极限承载力性状、平衡箱上下半段荷载-沉降曲线综合分析研究,揭示了桩底注浆对基桩承载性状的影响情况。According to the results of self-balance loading test of the grouting and no-grouting piles in the high-rise building, based on the research of the vertical pile ultimate bearing capacity of characters, and the load-settlement for the upper and the lower pile, Revealed at the end of grouting pile on the pile-bearing behavior of the impact of the situation.

关 键 词：桩端注浆 超长钻孔灌注桩 承载力
