چکیده مقاله:
Over the past decades some slopes were created inadvertently without considering any analysis and design criteria. Consequently, such slopes faced sliding problem due to service and other probable loads. In order to revitalize their stability and prevent catastrophic events, especially in public gathering places such as parks, reinforcing those slopes was considered as an inevitable solution. Due to the fact that reinforcing by using tieback system could decrease the plastic displacement of a slope, this type of anchoring system was chosen to handle slope instability problem. However, an essential question is that whether reinforced slopes have proper safety factor during a severe earthquake or not?In this paper, three slopes with different geometries in a park in Tehran are considered as case studies. After the slopes experienced sliding, they were reinforced with tieback anchors. Their stability situations have been examined by employing the finite element method.
