Slope Stability
Slopes tend to cause problems. Depending on their steepness, and other factors such as rainfall, weathered material naturally makes its way downslope, usually gradually, sometimes in sudden movements. In some situations, we take steps to prevent too much material moving downhill under these natural conditions.
More often, we create potential problems by creating slopes:

Movement downhill is caused by the force of gravity when the counteracting force of friction is overcome. It is
therefore important to recognise the part that the Maths and Physics play in slope failure if we are to create
solutions to the problem. These solutions involve reducing the effect of gravity by reducing the weight of the
material and by applying an "equal and opposite" force by providing support for the moving mass. We can also try
to increase the friction within the mass.
How can the Physics be turned into practical techniques for increase the stability of slopes? |

Geopix Study Topic "Slope Stability"
- explains the mechanics of mass movement and describes the various types of movement;
- describes the range of techniques used to increase the stability of slopes;
- illustrates these techniques by reference to the Panama Canal, Sorrento, Cape Town - and the M25.
