Control of the deformation response according to the ADECO-RS approachvance core by regulating its rigidity appropriately. In terms of forces this means employing preconfinement and not just confinement action, where preconfinement is defined as any active action which favours the formation of an arch effect in the ground ahead of the face.

The survey phaseround work must be preceded by activity, termed the ., to obtain that knowledge and this is performed by acquiring all possible information on the morphology, structure, tectonics, stratigraphy, hydrogeology, geotechnics, geomechanics and stress states, which characterise the geology of the body of ground in which excavation occurs.
