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.

Partial factors can be applied to soil strength and external loads in the PileLAT program as per the design requirements in Eurocode.

P-Y curves for weak rock in the PileLAT program are calculated using the method proposed by Reese (1997) and shown in the figure below.
