| 摘 要： | 普通预应力混凝土管桩在水平地震作用下抗弯能力较差;试验结果表明,设置填芯混凝土可以大幅度提高其抗弯承载力和延性性能;通过实验,推导出填芯混凝土抗裂弯矩和抗弯承载力的计算公式,可为工程计算和设计提供一些参考。

| Abstract: | The bending moment of common prestressed concrete pipe piles is relatively low under the horizontal earthquake action.The experiment results show that the concrete core in the prestressed concrete pipe pile has huge influence on improving its bending strength and ductility.The formula for calculating the cracking bending moment and bending strength of prestressed concrete pipe piles with the concrete core are deduced. |

| Keywords: | prestressed concrete pipe pile with the concrete core bending strength cracking bending moment |
