Causes Of Failure In Slope Stabilization

By Joseph Evans


Sheer strength and stress determine the balance within the gradient.The potential of slope covered to withstand and undergo movement is known as slope stabilization.Slope stability is a field that is analyzed and handled by geologists in different categories. They use their ability to interpret the surface of the earth to determine gradient stability through site observation. The article elaborates factors that affect or determine the stability of a hill.

One of the factors that lead to the failure of a hill being stable is soil erosion. Erosion has caused so may effect in mans life, and it has gone on to affect slopping land. When the soil on the hill is lost, it can be carried away by the wind, or it may slide down to the foot of the hill. This is bad and especially affects the people residing at the foot of the slope.

Another factor may be rainfall. This affects both the windward and leeward sides of the slopes. On the leeward side where there is no vegetation, the rocks that have gotten lost due to erosion may go tumbling down and clearing everything in their path. The wind ward side is which has the vegetation is so rainy, and the trees might be struck down by lightning and end up harming people and animals.

Earthquakes come about as a result of tectonic plates colliding with their movement or even breaking apart. Earthquakes, in general, have a devastating effect. If by chance they happen near an unstable hill the effect could be worse. This is because they could bring landslides that would destroy the lives and property of many.

Scientist like to learn about people and animals from the past. So they continually dig into the land trying to find evidence. This digging may lead to discontinuities and planes of weaknesses. The part that is weak will only require a small nudge to come down crashing. They usually crash in wards, so the real danger is the houses at the foot being lifted and pushed off the site.

There is the factor of external loading. This is basically the things that are on the hill. Some people actually live on slopes. If their weight plus that of their house and property becomes too much for the gradient to handle, it will eventually collapse, and everything on it will be destroyed. This is one of those hill failures that lead to losing of life.

A change in the topographical nature of a gradient may lead to it failing. Topography is the natural terrain of the land. The gradient may have had a vegetation at some point, but people with their own different interests cleared the vegetation. This would have changed the original form, and there will be consequences. This can be avoided by keeping the slopes as natural as possible.

The geometry of the hill. This basically means the height and angle of the gradient. The stability of a hill decreases with increase in height. This means that taller slopes are more dangerous as compared to shorter ones. A tall hill is also very steep, and therefore gravity does not do well on it. Anything on it is likely to fall off if not careful.
