大型碟簧桩帽的结构动力计算及其沉桩机理研究

Structural vibration analysis on the large disc-spring cap and its mechanism of pile driving

前一部分介绍了大型碟簧桩帽的结构动力计算方法及其结果；后一部分分析了碟簧桩帽的沉桩机理和现场沉桩的实测结果。计算和实测数据相比较，两者基本吻合。

Structural vibration analysis on the lage sisc-spring cap and its calculated results are introducedin the first part of the paper.The results of prototype driving test of a reinforced concrete tubular pile with disc-spring cap and the mechanism of pile driving are analysed in the ha part of the paper. The commpson of calculated results with tha of the field investigation shows tha they basically agree with each other.
