Influence du temps sur le comportement du gypse

Abstract : The underground quarry of Grozon gypsum shows instabilities that are a function of the exploitation age. Moreover, the minerals are strongly dissolved in the oldest districts. Concerning the physical properties and instantaneous mechanical behaviour, few differences are to be noted. However the time depended mechanical behaviour from this material is strongly influenced by the hygrometry. The more it is raised, the more deformation rate increase. The acceleration of deformation rate is also for the old working. A Lemaitre like creep law allowed some simulations.
