【摘要】 综述了由最初的普通钢筋混凝土抗拔(浮)桩发展到预应力抗拔(浮)桩的历程;总结了对于抗拔桩性能研究的3种方法:现场试验、模型试验和理论分析法。在此基础上为了降低成本,方便施工,环保高效,提出了一种新型的预应力抗拔(浮)桩,即部分粘接预应力抗拔(浮)桩,这将是预应力抗拔(浮)桩一个有意义的发展方向。更多还原

【Abstract】 The paper summed up the developing course from ferroconcrete uplift pile to pre-stressed uplift pile and three methods for study on property of uplift pile: field test,model test and theoretical analysis.On the basis of less cost,convenient construction and efficient environment protection,a new type pre-stressed uplift pile is put forward.更多还原
