    Geotechnical investigations conducted along the northern section of the Kalender Village highway have provided a detailed assessment of the regional rock materials and slope excavation conditions. Since the slope height in the region reaches 300 meters and the slope of the slope reaches 72 degrees, it poses a serious risk of rockfall. In the studied area, medium-thick layered limestone, sandstone and claystone rocks in different colors of gray and beige were observed. During the slope investigation, the rock materials were found to have undergone significant weathering and fracturing. This condition constitutes a significant factor that increases the risk of rockfall onto the highway. In areas where discontinuities are frequent and closely spaced, this risk is expected to become more pronounced. Particularly in weathered and fractured zones, further rockfall events may occur over time due to environmental effects.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Initially, a drapery system was installed in the fractured and weathered areas of the slope. A total of 58,000 m\u00b2 of Double Twisted Mesh (8×10 D27) was used in this application. This system limits the free movement of rock blocks, preventing them from falling onto the highway and enhancing safety for the road. Additionally, in high-risk zones, surface anchoring was applied for further reinforcement based on the geotechnical and engineering analysis performed with MACRO software. This additional support strengthens the slope’s stability and further reduces the possibility of rockfall. For larger rock blocks, dynamic rockfall barriers with a capacity of 3,000 kJ were installed based on rockfall analysis conducted using Rocscience Rocfall software. In total, 3,150 m\u00b2 of 3,000 kJ dynamic rock barriers (H: 5.0m) were installed in this project. These implemented solutions have significantly mitigated the risk of rockfall in the area and ensuring the safety of the highway.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
