Seismic Tomography and Ground Penetrating Radar Applied On Rock Slope Instability Analysis. Application On A Limestone Cliff In The Chartreuse Massif, France

Abstract: Evaluating the stability state of a rock slope is a complex problem, mainly due to the number of possible failure mechanisms, and to the lack of knowledge of the real present state of the rock mass. Geophysical methods appear as a useful tool for inves-tigating the deep discontinuity pattern, which is poorly known from surface observa-tions. However they have seldom been applied on steep rock slopes. The aim of this study is to test some of these methods on subvertical cliffs. We investigate the quality of information that they can ...
