What decreases the stability of a slope?

What decreases the stability of a slope?

Weathered geology: Weak, weathered bedrock, jointed rock, or bedrock that dips parallel to the slope can decrease stability. Vegetation removal: Droughts, wildfires and humans can remove vegetation from the slope, decreasing stability. Freeze/thaw cycles: Water in rock joints or in soils can decrease slope stability.

What are the geological factors affecting slope stability?

Slope stability is ultimately determined by two factors: the angle of the slope and the strength of the materials on it. In Figure 15.2 a block of rock situated on a rock slope is being pulled toward Earth’s centre (vertically down) by gravity.

How is slope stability calculated?

If the forces that resist the movement are greater than those driving the movement, the slope is considered stable. A factor of safety (FS) is calculated by dividing the resistance by the driving forces. A factor of safety greater than 1.00 suggests that the slope is stable.

What is a rock slope?

1. Inclined surface of rock surface. Learn more in: Determination of Stability of Rock Slope Using Intelligent Pattern Recognition Techniques.

How do you fix slope failure?

Below are some of the common methods used for slope failure mitigation and repair:

1. Drainage. Contractors who know what they’re doing will always draw up drainage plans to complement their slope repair plans.
2. Terracing & Benching.
3. Retaining Walls.
4. Friction Piles.
5. Sheet Piling.
6. Rock Bolts.
7. Shotcrete.
8. Geo-grid.

How do you make a slope less steep?

5 Steps for Erosion Control on Steep Slopes and Embankments

1. Plant Grass and Shrubs. Grass and shrubs are very effective at stopping soil erosion.
2. Use Erosion Control Blankets to Add Vegetation to Slopes.
3. Build Terraces.
4. Create Diversions to Help Drainage.

What are 3 factors that make slope failure more likely?

Common Causes of Slope Failure

• Steepness of the Slope. It goes without saying that the steeper a slope is, the more unstable it will be.
• Water and Drainage. Water is several times heavier than air.
• Soil Composition.
• Joints & Fractures.

What is an unstable slope?

Glossary Term. Unstable slopes. Slopes considered unstable due to their incline (or critical angle of repose), applied to slopes made of unconsolidated material. Unstable slopes are prone to failure in the form of rockfalls, rock flows, plane shears, or rotational shears.

How do you increase slope stability?

Slopes can be stabilized by adding a surface cover to the slope, excavating and changing (or regrading) the slope geometry, adding support structures to reinforce the slope or using drainage to control the groundwater in slope material.

What is rock slope failure?

Slope failures are essentially natural hazards that occur in many areas over the world. Popularly known as landslides, slope failures describe a wide variety of mechanisms that cause the outward or downward movement of slope-forming materials like rock, soil or landfills.

Is a 1 1 slope stable?

Long-term stable cut slopes in most soils and geographic areas are typically made with about a 1:1 or ¾:1 (horizontal: vertical) slope (Photo 11.2).

How do you increase the slope of a soil?

1. Work organic matter into the soil. Increasing the organic matter content improves the ability of the soil to retain water and the rate at which water is absorbed. Organic soil amendments could include manure, compost, sphagnum peat moss or grass clippings.
