What is geotechnical engineering?
When you build a piece of infrastructure it has to be connected to the ground. Geotechnical engineering is about understanding how the infrastructure interacts with the ground.
Geotechnical engineers deal with many types of infrastructure – tunnels, bridges, dams, buildings, roads, railways, ports and landfills – that are built on the ground. The ground nearly always has a complicated behaviour, whatever the type of soil or rock it is made of, so geotechnical engineering is very exciting and challenging – no two problems are ever the same.
