摘要
基于室内模型桩试验方法,结合灌注桩施工工艺对桩侧与桩端土体造成的影响,通过在桩侧设置泥皮与在桩端铺设石棉毡的方法分别控制桩侧与桩端土体承载条件,考察桩侧土体性质变化对桩端阻力的影响规律以及桩端土体性质改变时桩侧摩阻力的变化特征,进而揭示灌注桩桩端与桩侧土体相互强化的规律。
Based on the laboratory model experiment,according to the influence factors during the pile construction,the bearing condition of the pile-side soils and pile-tip soils is controlled by setting mire skin around the pile and asbestos at the bottom of pile.Then the influence regulation on the pile-tip bearing capacity and pile lateral friction is studied by the change of the condition of the pile-tip soils and pile-side soils respectively.By the experimental study,the commutative enhance mechanism is revealed.
