Geomechanical aspects of remediation of quarries in the flysch: Case study of abandoned quarry in Majdan, Croatia
As a typical example of cut slope in this region, an abandoned quarry in flysch rock mass in Majdan was selected, since it is intended to be reused as a recreation area. On the eastern side of the quarry slopes are up to 50 meters high and inclined more than 70 degrees, with large sandstone layers overhanging on the top. Considering that a solution with minimum investment was requested, which would also ensure both maximum space for recreation area, and sufficient safety factor for rockfall hazard, multiple scenarios and types of remediation measures were investigated. Detailed survey by terrestrial laser scanner (TLS) was made to ensure accurate profiles for 2D kinematic analysis, as well as to detect the erosion intensity and rate of scree accumulation at the bottom of the slope. Ground parameters necessary for kinematic analysis of future rockfalls were obtained by retrograde analysis of previously detected rockfalls on this and couple of other sites in the nearby area. Finally, a solution with two level gabion barriers was selected and presented which, in combination with periodical monitoring, provides the maximal usable space within budget constraints.
