Permanent ground deformation or ground lateral spreading is observed to be the main cause for the distress of piles embedded in liquefied ground. The purpose of this paper is to use uncoupled method for analysis of ground lateral spread effect on piles. The computer code, CYCLIC-1D (Elgamal, et al., 2002) developed at University of California at San Diego and accessible from the web, is used for lateral ground deformation estimation. Subsequently, the pile performance, treated as beam on Winkler foundation, is studied considering the effect of ground deformation obtained from CYCLIC-1D. Three centrifuge tested examples and one real field case were studied by the aforementioned method. Reasonable agreement was obtained between the predicted and the measured results.
