In this tutorial example, the use of the PileGroup program is demonstrated for analysing a pile group subject to TBM launching loading. This example involves a pile group consisting of 20 numbers of 1200 mm diameter CFA piles of 20 m long, which were spaced at three pile diameters in both directions.

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.

PileGroup is a finite-element based program which has been developed to calculate the deformations and loads of pile groups subject to general three-dimensional loadings such as axial and lateral forces and moments applied on the pile caps. The individual piles within the pile group can be vertical or on a batter with the connection between pile heads and pile cap to be fixed, pinned, or elastically restrained by rotational springs.

The implementation of p-y curve for Reese Sand in PileLAT is based on Reese et al. (1974) for both static and cyclic loading conditions.

We are pleased to announce that PileGroup Version 2.3 is released in September 2021 with the following improvements and updates compared to

The lateral load behaviour of a 16-piles group was studied by Ruesta and Townsend (1997) in Stuart, Florida. The pile group was composed of

A wide range of p-y curves are available in PileLAT and PileGroup programs for modelling behaviour of soils and rocks under lateral loading.
