Contribution to Phenomenon of Sechage-Humidification of a Clay Soil of Algiers: Case the Argillaceous Marnes

F. Z. Aissiou and A. Nechench

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.

Index Terms—Dryness-humidification, risk, argillaceous Marnes of Algiers.
