Landslide remediation between Kvaternikova and Divoselska street in Zagreb
On the slope between Kvaternikova and Divoselska street in Zagreb landslides have been activated after heavy snowfall in mid-January 2013 that threaten surrounding residential buildings and water, gas and sewage infrastructure in Kvaternikova Street. According to residents whose houses were threatened by landslides first cracks on slope surface were noticed in the summer of 2012 after a long dry period. Unfavorable weather conditions in 2013, snow melting and rain caused the progression of sliding and on the landslide surface it created loosened soil material with high water content. Accessing the landslide with heavier machinery was not possible and in accordance with such a situation on the site and the available technology emergency measures were implemented that included the drain trenches and driven wooden piles from local wood. Implemented emergency measures prevented the collapse of road, sewage, gas and water supply as well as sliding and launching larger landslide mass. In the next phase detailed design were made in which remediation of the entire landslide was planned. For the purposes of the design for landslide remediation insight into the existing geological maps and earlier investigations was made and geotechnical investigations were conducted. Final landslide remediation measures included the construction of retaining wall with strand anchors and foundation on piles along the road, shifting soil masses on the slope, gabion wall in the lower part of the slope, construction of drain trenches and planting vegetation. In order to control performance of landslide remediation and record side effects that require additional remedial measures, monitoring was carried out. In this article are presented all the phases of the landslide remediation in chronological order from the investigation works, emergency remedial measures, detailed design documents, construction phase and monitoring.
