Liquefaction factor at the end of the earthquake
Given the very limited number of major earthquakes recorded in France, it is not
surprising that the question of uncertainty over the seismic signal is raised. For this
reason, a parametric study on the seismic hazard effect was carried out.
The objective of this part of the study is to determine the strongest acceptable
earthquake, defined by its maximum acceleration, which would damage the
embankment without leading to its complete destruction, for a given mean relative
density of the soil constituting the structure. For this purpose, the embankment is
subjected to the same accelerograph and a parametric study of the maximum
acceleration is performed. The results are presented in Figure 10.20.
