摘要
通过静载荷试验和桩身轴力测试,对比了注浆及未注浆两种情况下灌注桩承载性状,说明桩端注浆后大大提高了软土地区钻孔灌注桩的单桩承载力。最后分析了注浆后桩侧摩阻力、桩端阻力提高的原因。
According to the static load test and pile shaft axial force test,the bored pile bearing behavior under two conditions of grouting and non-grouting have been made a comparison.The results showed that pile bottom with grouting could increase the single bearing capacity largely of bored piles in soft soil area.Then,the increased reason of side friction of pile and pile bottom resistance after grouting has been discussed in the paper.
