Studies of landslides

Clay embankments, both natural and artificial (such as when constructing a motorway), often have failure planes linked with the creep of certain levels.

Surveys of the soils and auger or core drilling are used to provide an accurate assessment of the thickness and nature of the different levels, as well as to take samples.

These samples are then put through all the laboratory tests required (Casagrande shear test, Atterberg limits, triaxial test...) to obtain the parameters necessary for the calculations.

All the results are then analysed to determine the safety factor and the possible reinforcement solutions, if necessary.
