Analysis of full-scale tests on piles in deposits subjected to liquefaction
This paper describes results and analysis of shaking table tests on a prototype-scale soil-pile model. A model of pile foundations embedded in saturated sand was used to investigate the performance of piles when surrounding soils undergo liquefaction during earthquakes. It is shown that the lateral soil displacement of the liquefied layer and the pile head fixity condition are key parameters influencing the pile response. A reasonably good agreement is found between the experimental results and theoretical predications by an effective stress method of analysis.
