Results of the first geo-mechanical experiment: emplacement of the Mont Terri ramp. a Prototype composed of a Meso-Cenozoic sedimentary cover on top of a Triassic evaporitic décollement (white dashed line), lying above the basement. b Graph of the results obtained after applying a compressive force on the southern wall depending on the friction angle on the Triassic décollement. The red rectangle highlights the range of friction angles on the décollement for which the result obtained is the one expected by the geometrical scenario. c Illustration of the different results obtained and presented in (b).
