ABSTRACT
The collapse of Cheria in Eastern of Algeria which occurred in 2009 constitutes a good example. In the latter, a great collapse was recorded, in which tens of constructions were inserted of more than two meters and half in the ground. While waiting to achieve measurements of the technical expertise, the preliminary report charges this catastrophe to a movement in the ground water. A geotechnical study made by Batna (2000), within the scope of the realization of a natural gas station in Hassi Messaoud shows that the site is composed of two layers of collapsible nature, the adopted solution is substituting the first layer and taking measures to avoid the infiltration of water to the second layer. In addition, degradations of several residence buildings which took place in Biskra (2002) are due to water infiltrations. A building of three floors with Xining, Qinghai, was destroyed beyond repair because of collapse Qian & Lin (1988). This problem occurred because the loess beneath the foundations underwent a structural collapse when it was flooded. Experimental and theoretical studies aiming to understanding the great number of uncertainties implied in the phenomenon of collapse are currently undertaken. The literature revealed that the majority of research was devoted to the collapse mechanisms and the identification methods, of treatment and prediction.
