LEYNAUD Table 7). Static and pseudo-static approaches provide similar FOS (1.72/1.85/1.74, static; 1.08/1.13 pseudo-
2、static). The FE dynamic estimate gave a safety factor lower than 1.0 for a failure surface up to 40 meter depth (0.1 g PGA). Using the Monte Carlo simulation and FORM methods (pseudo-static case) we obtained the following probability of failure (Table 8). 10 Conclusions Backcalculation of the slide:
3、 1.A high FOS is found for the static case (FOS=15.0) which means that the continental slope (1 degree slope angle) is very stable if subjected only to gravity loading. Assuming a slope angle increase up to 3 degrees, the static FOS is reduced to 4.39 (very stable slope). 2.From the pseudo-static mo
4、del, the pre-slide area is unstable with a 0.15 g pseudo acceleration. Considering a similar value for the PGA and the age of the slide (4300 y. BP) on the other hand, this is in accordance with the seismic activity in the area (0.35g PGA, 10000 year return period). The Finite Element method model a failure in the first 20 meters depth (FOS=0.77) showing that the dynamic earthquake-induced shear stress is enough to initiate some failures at medium depth during the first 10 seconds. Thus, if the
