Slope mechanical modelling: Contribution of multi-geophysical imagery

Abstract

This work aims at assessing the impact of local heterogeneities consideration in slope mechanical modelling. We choose to use different geophysical techniques to characterize these heterogeneities, and a fuzzy logic data fusion concept to create a geometrical model from these data. The first mechanical simulation, realized with basic elastic constitutive law, gives a surface displacement pattern in agreement with the one measured. This highlights the importance of the model’s layer geometry on the results and also the suitability of geophysical imagery tools to constructs high resolution geometrical models. .
