桩底注浆对钻孔灌注桩竖向承载性能的影响
摘要:依据某工程中采用桩底注浆和没有注浆的2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,揭示了桩底注浆对基桩承载性状的影响情况。
Abstract:Based on the results of vertical static loading test of piles in the high-rise building, the influence of base-grouting on the bearing properties of pile is revealed by analyzing its properties of vertical limiting bearing capacity, axial load transmission and tip and shaft resistance of pile, load transfer performance and bearing mechanism is discussed in detail. In the end, a conclusion is deduced that the base-grouting is inevitable development trend of bored piles in Shanghai soft clay area.
