Accès restreint aux membres de l'Université de Lorraine jusqu'au 2016-12-30The risk of instability of underground structures (natural or anthropogenic) involves over 10 000 towns in France. The accidents due to the sudden collapse of underground quarries are among the most destructive, both humanly and materially. The evolution of possible instabilities, since the issues are significant, implies to enrich current knowledge to predict their extent and their impact on the surface. Previous work has demonstrated the importance of the hydro-mechanical coupling in the diagnosis of stability. The complexity of the chalk-water interaction phenomenon is due to many environmental factors and sensitivity to each factor depends entirely on the chalk c...
