Brebornica landslide remediation design
The Brebornica landslide is located southwest of the village of Brebornica, on the state road DC1, section 011, at km 4+500. For this project we carried out the engineering geological and geotechnical investigation and testing and made the main and detailed landslide remediation design. During the execution of the works, we also carried out the complete supervision of the remediation.
In December 2020, the earthquake in Banovina activated the sliding of already unstable road material and caused a crack to open of a height of approx. 2.0m. An inspection in the field has found that the landslide had progressed as was evident from the additional settling of material, accumulation in the reservoir in the southeast direction, seeping of water at the bottom of the reservoir, dredging of the terrain and leaning trees.
As part of the Brebornica landslide remediation design on the state road DC1, section 011, at km 4+500, our design included the planned works aimed at increasing the overall stability of the slope, the construction of a rainwater drainage system, and the reconstruction of the road. Landslide remediation included the implementation of the following remediation measures:
– construction of pile wall from reinforced concrete drilled piles;
– construction of a drainage system; and
– road reconstruction.
Two inclinometers of a length of L=12.0m were installed for the monitoring of displacement during the road remediation.
