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 are the factors influencing slope failure?
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 3 types of slope failure?
Types of slope failure in geotechnical engineering
- Rotational failure. When rotational failure occurs, the failed surface will begin to move outwards and downwards.
- Translational failure.
- Compound failure.
- Wedge failure.
What are the three factors involved with slope?
Slope stability is affected by the following factors. Strength of soil and rock. Type of soil and stratification. Discontinuities and planes of weakness.
What increases the odds of slope failure?
External processes that increase the odds of a slope failure include: (1)steepening the slope; (2)removing support from low on a slope; as by stream or ocean-wave erosion; (3)adding mass high on a slope, as in sediment depositon.
What are four typical causes of slope failure?
Causes of Failure of Slopes
- Gravitational force (Creep)
- Force due to seepage water (Swelling / Leaching)
- Erosion of the surface of slopes due to flowing water.
- The sudden lowering of water adjacent to a slope (Rapid Drawdown)
- Forces due to earthquakes.
What are the five 5 factors influencing slope stability?
Five factors influence slope stability of an embankment: 1) Shear strength of the soil; 2) Unit weight; 3) Embankment height; 4) Slope steepness; and 5) Pore pressure within the soil. Failure generally occurs in two ways.
What are the 4 modes of failure?
For mechanical devices, there are four Failure Mechanisms: corrosion, erosion, fatigue and overload. While those Failure mechanisms exists many places in nature, they may or may not be present in the specific working environment of an asset.
What are the 3 examples of slope forming materials?
The term “landslide” describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these.
What are the common modes of failure?
One precise definition of CMF is: “a common mode failure is the result of an event(s) which because of dependencies, causes a coincidence of failure states of components in two or more separate channels of a redundancy system, leading to the defined systems failing to perform its intended function”.
What are 3 other names for slope?
slope
- incline.
- inclination.
- gradient.
- diagonal.
- climb.
- pitch.
- lean.
- ascent.
What are the 4 slope elements?
Characteristics of the slope elements: crest, cliff, talus and pediment.
What are the three factors of erosion?
Factors Impacting Erosion Some of the natural factors impacting erosion in a landscape include climate, topography, vegetation, and tectonic activity.
What are 2 factors that impact the stability of a slope?
Slope stability is ultimately determined by two factors: the angle of the slope and the strength of the materials on it.
What are the causing factors for slope failures or landslides?
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
What type of slope failure are common in soil?
Toe failure is the most common failure in which failure plane passes through of . Base failure occurs when there is a weak soil under the toe and failure plane passes through of .
What human activities cause slope instability?
Humans greatly affect slopes negatively, for example, by mining, construction and farming. While humans are the culprits of affecting slopes negatively, they’re the ones who can modify slopes to stabilise them, for example, terracing.
What are the 3 main factors which can lead to failure of a person?
Here are the most common failure-causing problems and their solutions:
- Lack of persistence. More people fail not because they lack knowledge or talent but because they just quit.
- Lack of conviction.
- Rationalization.
- Dismissal of past mistakes.
- Lack of discipline.
- Poor self-esteem.
- Fatalistic attitude.
What are three 3 causes of material failure?
The usual causes of material failure are incorrect materials selection, incorrect processing, incorrect manufacturing procedures, inadequate design or incorrect use.
What is the main cause of failure?
The main causes of failure in life are poor environmental influences, the wrong mindset, bad habits, and lack of motivation. All these reasons for failure can be addressed if you identify which ones apply to you and create a plan for removing them.
What are the 4 types of slopes in geography?
characteristic slopes
- convex slope segments. form on the upper parts of slopes in response to soil creep and rainsplash erosion, when slopes are below the threshold for rapid mass wasting.
- concave slope segments.
- straight slope segments.
- composite slopes.
