Abstract:

Soil liquefaction induced by earthquake will cause very large damage to structures, especially to the pile foundations. Pre-stressed high-strength concrete (PHC) pipe-piles were regarded as the relatively economic and effective piles in practical engineering. However, the failure modes of PHC pipe-piles and the interaction of soil-pile with or without liquefiable soils are still unclear. A testing on the seismic failure mode of PHC pipe-piles in liquefiable soils had been conducted under shaking table. The PHC pipe-piles were employed and tested under a series of sine and El Centro earthquake waves as well as artificial ground motions based on in-site, and the particular attention was paid to the failure mode of the piles and basic experimental phenomena during soils liquefaction. The testing results demonstrate that the presence of prestress can significantly improve anti-seismic shear forces and the failure modes of PHC pipe-piles in liquefiable soil have a little different. © ASCE.
