4. B modeling#
4.1. Characteristics of modeling#
Modeling B uses a behavior model for the linear embankment, the calculation of the initial stresses using the operator MECA_STATIQUE and the dynamic calculation using DYNA_VIBRA. The evaluation of the safety factor is carried out by the macro command POST_NEWMARK directly by providing the radius and coordinates of the sliding circle.
We activate the option to check the mass of the sliding zone, with a relative error RESI_RELA of 2%.
4.2. Tested sizes and results#
The value of the seismic coefficient \({k}_{y}\) obtained by the macro-command is tested by comparing it to the value estimated by the GeoSlope software and used as input to the modeling A.
