Abstract:

The Interaction factor method is a kind of effective numerical methods to analyze pile groups; and the key point of this method is to get the interaction factors. The parameter computed by the traditional elastic method is lager than the real interaction. The new method to compute the interaction factors by the FEM considering the pile soil sliding and the elastoplasticity of soil is presented; and the simplified analysis method of pile groups is established. The influences of various parameters on interaction factors are studied by ABAQUS. Different methods are compared on the two history cases; and the results show that the new method by FEM is more suitable for the analysis of the real engineering cases.

Key words: interaction factors, pile group, FEM, simplified analysis
