skråningssikring

Skråningssikring refers to the methods and techniques used to stabilize and prevent the failure of natural or man-made slopes. Slopes are susceptible to instability due to factors such as gravity, water infiltration, seismic activity, and erosion. The primary goal of skråningssikring is to maintain the integrity of the slope, preventing landslides, rockfalls, and other forms of mass movement that can pose risks to infrastructure, property, and human life.

Various approaches exist for skråningssikring, broadly categorized into passive and active methods. Passive methods aim to mitigate the consequences of slope failure, such as by installing barriers or catch fences to intercept falling debris. Active methods, on the other hand, focus on improving the inherent stability of the slope itself. This can involve measures like altering the slope geometry through regrading or terracing, improving drainage to reduce pore water pressure, or reinforcing the soil or rock mass.

Common techniques for active skråningssikring include the installation of retaining walls, soil nailing, rock bolting, geogrids, and vegetation. Retaining walls are structures built to hold back soil or rock. Soil nailing involves inserting steel bars into the slope to reinforce the soil mass. Rock bolting anchors rock masses together. Geogrids are geosynthetic materials that provide tensile strength to the soil. Vegetation, through its root systems, can help bind soil particles and reduce erosion. The selection of the appropriate skråningssikring method depends on a thorough geotechnical investigation of the slope's characteristics, the anticipated loads, and the desired level of safety.
