STABILISATION OF CUT 3, LOT 1, SECTION GORJE POLJE – CARIČINA DOLINA, E-75 HIGHWAY, BELGRADE – NIŠ, PHASE II, REINFORCED SOIL CONSTRUCTION

Abstract

During the execution of works on the E-75 highway, Belgrade-Niš - the border with FYR Macedonia, on section Gornje Polje - Caričina Dolina, LOT 1, on the Cut 3 from km 876+ 325 to km 876 + 825 there was a violation of the stability of a conditionally stable slope that jeopardizes the highway route. According results of extensive geotechnical investigations it is a huge landslide with a complex slip mechanism. Within the Phase II works on the stabilization of the landslide toe in the zone of the left bank of the South Morava River, in the length of 300,50 m, from km 3 + 592 to km 3 + 900.35 (along the axis of the river), or from km 876 + 739,23 to km 876 + 485 (along the axis of the highway) are foreseen. These works consist of constructing the reinforced soil embankment, up to 12.5 m height in the zone of toe of the landslide. The embankment shall contribute to the stabilization of the slope as a ballast, as well as redistribution of the mass after the excavation necessary for the road deviation.
