Penetration of a single steel foundation pin in a granitic rock
Development of a subsea tidal turbine requires specific research to design the foundation in contact with the seabed. The design stage can be simplified using numerical modelling and more specifically discrete modelling. HydroQuest commissioned Cathie Associates to simulate the behavior of a single foundation pin in a granitic rock mass using Itasca’s discrete numerical approach PFC3D. Itasca France developed the numerical model and routines to track the evolution of the forces applied to the pin as well as the zone of damage around the tip of the foundation during penetration. Two key stages were simulated within the model: the installation phase (vertical penetration) and the operational phase (shearing due to swell).
The model was able to validate theoretical values of the vertical pressure required to penetrate the rock for different sets of material properties and multiple realizations of fracture network. The pre-existing fractures had a major influence on the mechanical behavior and fracture propagation mechanism. The figure below illustrates the evolution of the reaction force on the pin during the horizontal loading, and large variations can be observed due to pre-existing fractures and damage propagation in the rock mass.

Stability calculations for small slopes
ITASCA Consultants GmbH was commissioned to demonstrate the stability of embankments in a stratified soil as part of the expansion of a small shopping center. The embankments concern a slope and a rain retention basin (RRB). An additional traffic load is applied to the left edge of the model. The following figure shows maximum shear strain for a stable factor of safety of 1.42 using the cross section of the RRB as an example. The maximum shear strains show the possible failure mechanisms of the embankment. The simulations were performed with FLAC3D version 6.0.
