摘　　要：由于抗拔桩的工程应用越来越广泛,在分析抗拔桩工作机理的基础上,提出抗拔桩在实际工程中受地下水位高低以及地下水范围的影响,存在抗压和抗拉2种受力模式,相应的抗拔桩筏基础也存在这两种受力模式,即上部结构荷载作用下底板受压和水浮力作用下底板抗浮。并结合工程经验,提出了在这2种工况下,抗拔桩筏基础底板配筋的计算方法。As the development of underground buildings and underground space, the uplift piles are used more and more widely in all kinds of civil engineering. On account of analyssing the working mechanism of the uplift pile, the two stress patterns of the uplift pile which effected by underground water level and groundwater range in the practical engineering are proposed： resist compression and tensile. The corresponding, the raft foundation based on uplift pile also has two kinds of force mode, namely the pressure from the upper structure load and the tensile by the buoyancy of groundwater. Based on the experience of projects, in the two conditions that mentioned above, the reinforcement design methods of raft foundation bottom based on uplift pile are proposed.
