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

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.
