Abstract

In order to give an insight into the seismic responses, pile-soil interactions as well as failure modes of PHC pipe-piles in the coastal soft-soil area, tests on the PHC piles-soil-structure model system under the shaking table were conducted. Different prestress ratios and soil properties were considered to investigate the influence on seismic response and failure mode of PHC pipe pile-soil-structural model system by increasing the peak values and inputing three different earthquake waves. The results indicate that soil saturation has a significant effect on the dynamic parameters and seismic responses of the model system, and the prestress ratio has a certain influence on dynamic properties. The failure modes are different as for the unsaturated soil, the natural frequency of PHC model system slightly decreases under the basic intensity. While for saturated soil, the natural frequency of model system decreases to 50% of the initial frequency with the increase of peak ground acceleration (PGA), which indicates that the model has damage or even failure under the rare intensity. Moreover, the damping ratio and interaction of structure-soil-pile of PHC model will increase. However, the existence of prestress can significantly mitigate the effect of earthquake. In addition, the pore water pressure increases to 1.0 and is liquefied with the increase of PGA and the soil depth, and the duration of liquefaction is far longer than the seismic wave history. The results can provide the basis for the application of PHC pipe-piles in coastal soft-soil area and the implementation of seismic code.
