THREE-DIMENSIONAL ANALYSIS OF PILE GROUPS.

Abstract

A numerical method is presented for the analysis of general three-dimensional pile groups. The features of the pile-group model may include battered piles, different pile sizes, non-uniform pile sections, soil nonlinearity, soil inhomogeneity, and pile-soil-pile interaction. A typical six-pile group is analyzed and compared with results from three other computer programs for pile-group analysis that are based on different approaches. This method is then used to analyze field and laboratory tests on groups of battered and vertical piles. The computed solutions are shown to be in good general agreement with the measured data.
