heal.abstract	When soil liquefaction occurs in slightly sloping ground or near free-face topographic irregularities large horizontal displacements may occur due to the lateral spreading of the liquefied ground. This kind of ground failure may cause extensive damage to pile-supported structures as witnessed in several recent earthquakes (Chi-Chi 1999, Kobe 1995, etc). A systematic analysis of the detrimental effect of lateral spreading requires a sophisticated 3-D numerical analysis. Still, there is need for preliminary estimation of the response of deep foundations based on readily available data, such as the geometric and the mechanical characteristics of the foundation and the maximum anticipated displacement at the ground surface. For this purpose, a set of over 200 parametric numerical analyses were performed, with the pseudo static P-y method, in order to analyze the basic parameters affecting the pile behavior. The results of the parametric analysis have been consequently combined into design charts for the computation of the maximum developed pile head displacement and moment. © 2009 IOS Press.	en
