Abstract
Consecutive differential movements of ground to the dryness and the rehydration of the sols" are irregular movements of ground related to the phenomenon of withdrawal-swelling of clays. They appear in the clay soils and are related to the water variations of the ground. These movements are slow and involve a progressive deformation of the grounds, not always perceptible by the man. During the periods of dryness, the lack of water involves the retractation of clays: there is a phase of withdrawal. Contrary, a new contribution of water in these grounds produces a phenomenon of swelling. By risk of withdrawal-swelling, one understands the phenomenon "natural" likely to occur, with a probability of more or less large occurrence. For the phenomenon of withdrawal-swelling of the argillaceous grounds, one will speak about strong, average or weak risk. This article returns within the framework d' study of risk withdrawal - swelling or dryness-humidification of the argillaceous marnes of the area of Ouled Fayet and Chéraga of Algiers.
