Sažetak
The rock sliding occurred in the Republic of Kosovo, in February 2017, on the part of motorway under construction. Landslide mass, in the area of 0.9 ha, came down the slope above viaduct piers in construction and pushed on them. The immediate result was the tilting and structural failure of viaduct’s pier. Following the event, extensive soil investigation works were carried out and remediation were proposed. Rock slide happened on mountain section, where terrain is composed of tectonically crushed gneiss rock and weakly bound and unbound deluvial sediments and colluvium masses. Accepted solution included removing damaged piers and construction of new ones, with protection, retaining structures, which would resist sliding mass and protect piers from its influence (Szavits-Nossan, 2009). In designing, 2D geotechnical and 3D structural models were used to predict behaviour of arch shaped retaining structures. Designing was supported with monitoring from site and the works successfully continued.
