摘要
预应力双向组合式碟簧桩帽能够较大幅度地降低应力峰值，延长作用时间，有效地保护桩身和桩头的完整。通过采用结构动力学原理分析，揭示了双向组合式碟簧桩帽的动力学机理。并用现场沉桩的实测值验证了理论计算的结果。
Structural Vibration analysis on the prestressed disc-spring cap and its calculated results are introduced in the first part of the paper.The results of prototype driving test of a reinforeed concrete tubular pile with disc-spring cap and the mechanism of driving are analyzed in the last part of the paper,The comparison of calculated results with that of the field investigation shows that they basically agree with each other.
