摘要
钻孔压浆桩是一种新型端承—摩擦灌注桩,其承载能力要明显高于其他钻孔灌注桩。根据与相近场地条件钻孔灌注桩的实际测桩结果所作的对比分析,钻孔压浆桩可以形成较高的侧摩阻力,在极限荷载中,侧摩阻力的构成比达65% ~75% 。
Pressure grouting pile is a new kind of grouting pile,whose bearing capacity made up end bearing and side friction.The pressure grouting pile has higher bearing capacity than other kinds of grouting pile,and it consists principally in frictional resistance.65%~75% of ultimate bearing capacity of pressure grouting pile comes from the side friction based on analyzing the proportion of frictional resistance to end bearing.
