Ground-fluid-structure interaction

 

We focus mostly on dynamic problems where the soil moves around structures, e.g. earthquakes or landslides, or problems where the structure move over or within the ground, e.g. robots, soil probes. etc.

Using the most advanced computational techniques we carry out studies on the interaction between fluids, the ground and structures within it or above it. We can use in-house solvers in SPH, MPM, and FEM, or commercial software such as PLAXIS, ABAQUS, LS-DYNA or PFC, to name but a few.

Application areas are:

 
  • Landslides and debris flows

We carry out model tests and numerical models of debris flows and their interactions with structures, such as tunnels or obstacles.

  • Tunnels under seismic loading

Working with international partners our work in this area focusses on state-of-the-art physical models, such as shaking table tests or centrifuge testing, together with simpler model tests, but also on instrumentation and numerical models.

  • Computational Geomechanics & Machine learning

The integration of new machine learning techniques into ground engineering in general is a rapidly developing new field where we can use our expertise in machine learning and ground engineering to develop bespoke solutions. In particular, we are interested in data-centric numerical modelling and physics-based machine learning solutions applied to geomechanics and tunnelling problems.
