In this tutorial example, the use of the PileGroup program is demonstrated for analysing a pile group in sand. This example involves a 4 x 4 pile group consisting of 16 numbers of 760 mm diameter driven prestressed concrete piles of 16.5 m long, which were spaced at three pile diameters in both directions.

In this analysis mode, the approximate closed form solutions for single piles subject to axial loading (Randolph and Wroth 1978a and 1978b)
