Factors affecting slope stability
Slope stability is affected by the following factors.
- Strength of soil and rock.
- Type of soil and stratification.
- Discontinuities and planes of weakness.
- Groundwater table and seepage through the slope.
- External loading.
- Geometry of the slope.
Causes of slope failure
Following are different causes of slope failure.
- Erosion.
- Rainfall.
- Earthquakes.
- Geological factors.
- External loading.
- Construction activities such as excavation of slopes and filling of slopes.
- Rapid drawdown*.
- Increment of pore water pressure.
- The change in topography.
*Drawdown : a lowering of water level.
Methods to improve and protect slope stability
Slope stability can be improved by taking following actions.
- Slopes are made flattened or benched.
- Weight provided at toe.
- Lowering of ground water table to reduce pore pressure in the slope.
- Use of driven or cast-in place piles.
- Retaining wall or sheet piling provided to increase resistance to sliding.
does climate have any effect on slope stability?
Obviously climate have effect on slope stability. Climatic factors such as rainfall causes slope failure and affecting slope stability.
hye..i wish someone may help me answering this..what is the meaning of geological factor affecting existing/natural slope..anybody?..admin?
Boom!
