The stability of earthworks (cuttings, embankments, dikes) and natural slopes\nis a problem that is of concern to geotechnicians, both practitioners and researchers.\nThe disorders generated by breaking the slopes are usually spectacular,\noften destructive and sometimes murderers. Many methods of calculating\nstability have been proposed. These are differentiated by the assumptions\naccepted by their authors (methods of calculation in equilibrium limit,\nmethods of calculation at break, deformation calculation methods) and the\nease of their implementation (calculations using charts, automatic calculations\nusing software), but they all agree to define an overall factor of safety according\nto which the stability of the studied slope is considered to be insured or\ncompromised, or by safety factor spartial effects on the one hand, applied\nstresses and, on the other hand, the mechanical properties soil. Various embankment\nstrengthening techniques have been developed. They are differentiated\nby the process of their realization, their cost and their durability. The\nmain objective of this study is to present the problems of both natural and artificial\nslope stability on construction projects. In this regard, special emphasis\nis given to the sensitivity of the calculation model input parameters (soil, load),\nwhich should contribute to raising awareness about this issue, as a prerequisite\nto make the right decisions and optimal technical solutions in this area.
