抗拔（浮）桩的发展历程和研究方向

Development and Research Direction of Uplift Pile

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。

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.
