Abstract
Localised landslide activity has been observed in the area of the plateau slope analysed, in the vicinity of the planned
Warsaw Southern Ring Road. Using calculation models quantitative and qualitative evaluations of the impact of natural
and anthropogenic load factors on slope stability (and hence, safety) are made. The present paper defines six stages
of slope stability analysis, leading to an indication of optimum slope design in relation to the development planned.
The proposed procedure produces a ranking of factors that affect slope stability. In the engineering geological conditions
under consideration, the greatest factors impacting degradation and failure of slope stability are changes in soil
strength due to local, periodic yielding and the presence of dynamic loads generated by intensification of road traffic.
Calculation models were used to assess the impact of destabilisation factors and to obtain mutual equivalence with
3D-visualisation relations. Based on this methodology, various scenarios dedicated to specific engineering geological
conditions can be developed and rapid stability evaluations of changing slope loads can be performed.
