Rock Slope Stability

Rock Slope stability studies assess potential rock slope failures as a result of planar geologic conditions, such as strike and dip, joints, and faults. These studies require measurements of geologic features at nearby bedrock exposures to assess the potential for failure along discontinuity planes. The field data are plotted using stereonets to assess the structural data and complete Marklands test. Marklands test allows GeoServices to determine where potential rock slope failures may occur.

Rock Slope Stability Analysis Uses

The rock slope stability analysis is useful for land developers in that GeoServices can determine the maximum cut slope angle that will remain stable at the site, allowing for better site utilization. Additionally, the results of the analysis can be used by developers and land planners to determine the best location for driveways or cut slopes to maximize land use or to minimize potential rock slide hazards.

Benefits of a Rock Slope Stability Analysis

The benefits of a rock slope stability analysis include:

  • Demonstrate that steeper slopes than specifically allowed by ordinance are safe and appropriate, which may reduce excavation costs as well as minimize the area of disturbance.
  • Improve the orientation of cut slopes to minimize potential rock fall hazards.
  • Minimize excavation and slope stabilization costs.
  • Improve safety of cut slope faces.
