Decomposition of dynamic p-y curves considering liquefaction during earthquakes

There is an established fact known that, there is a relation between the p-y resistance of piles and liquefaction formation. To investigate this fact, a single pile foundation in liquefiable soils composed of liquefiable sand and overlying soft clay was subjected to sinusoidal shaking motions will be tested. That is the basic purpose of this study was to analyze and construct a p-y curve of liquefied soil under different shaking loading conditions companied with the effects of several key design parameters were undertaken to understand the effect of pile characteristic and pore water pressure response in the zones of responding area.
