Axial Interaction between Dissimilar Piles in a Group
The paper describes the results of an investigation into axial interaction among a group of dissimilar piles. Consideration is given to the settlement and load distribution in a group containing piles of different section or length, arranged in any general configuration, and subjected to static or cyclic axial loading. Solutions are presented for a circular eight pile group, for the following cases: (a) some piles in the group have belled bases, (b) some piles have different lengths or diameters, (c) some piles have reduced stiffness (to simulate construction defects). Under cyclic loading, it is found that degradation of skin friction begins at lower load levels in a group with dissimilar piles than in a group of identical piles. Degradation of the 'weaker' piles occurs first, with a subsequent redistribution of load to the 'stronger' or stiffer piles.
