Abstract EN
In order to investigate the applicability of dynamic stiffness for bridge cap-pile system, a laboratory test was performed.
A numerical model was also built for this type of system.
The impact load was applied on the cap top and the dynamic stiffness was analysed.
Then, the effect of the effective friction area between pile and soil was also considered.
Finally, the dynamic stiffness relationship between the single pile and the cap-pile system was also compared.
The results show that the dynamic stiffness is a sensitive index and can well reflect the static characteristics of the pile at the elastic stage.
There is a significant positive correlation between the vertical dynamic stiffness index and bearing capacity of the cap-pile system in the similar formation environment.
For the cap-pile system with four piles, the dynamic stiffness is about four times as large as the single pile between 10 and 20 Hz.
