Abstract(s) :
(Anglais) Stability assessment of an abandoned underground chalk quarry, named Malogne, has been conducted. For that reason, a parametric study with the geomechanical software RS2 was performed where three sets of data for the rock mass properties were consider. As a result, the values for the maximum principal stress and the Strength factor were obtained and the overstressed areas of the rock mass were identified. Furthermore, the in situ observations and comparison with the numerical model results shows a good correlation between the prediction of the models and the current behaviour of the rock mass.
