Um modelo para a interacção em lajes fundadas sobre grupo de estacas

Resumen

Based on the considerations of pile interaction as published by Randolph and Wroth (1978) and Van Impe (1991), a modified interaction model for a piled raft foundation system anda layered soil profile is proposed. Attention is payed particularly to the pile soil interaction radius and the relative stiffness of the pile group and raft. The paper shows the application of the model for a case study in France.
