Factors Affecting Leading To The Failure Of 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.

A slope cannot be stable if it is constantly experiencing soil erosion. This is because it will not be complete. It will be weak as it loses the soil each time the wind blows. The erosion is not only a disadvantage to the gradient but to the people around it too. The soil is carried towards them, and it interferes with their livelihood by for example getting into the water.

Rainfall is another issue. A slope has two sides. The side with the rain and the side that is dry. When it rains on the dry side, there actually might be a mud slide. It may be accompanied by several rocks rolling downhill. On the rainy side, the rain may not be very bad but at times, it is too strong, and branches of trees may end up in the homes of people.

Earthquakes are dangerous in general. They are caused by tectonic plates hitting each other or breaking apart. The earth tremor may result in a number of calamities. There may be a land slide that will cover everything on the foot of the gradient. Landslides have been known to end lives and destroy property worth a lot.

There are activities like an excavation. These involve machinery being drilled into the ground and messing with the rock arrangement. A rock may get drilled into half and result in the collapsing of a whole section of the hill. It may cause further damage by causing discontinuities and planes of weakness which only need a little movement to come crashing down.

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.

Change in topography is also another factor. This can come about of deforestation. Lack of vegetation weakens the ground, and it can be affected in so many ways. Those large rocks that have sat on each other for thousands of year may just lose their grip and roll downhill. The best solution for these is to ensure the hill remains how it is supposed to be.

The geometry of the slopes is a highly contributing factor. Short gradients are much safer and less steep compared to tall ones. There are roads built around slopes, and the tall slopes are likely to have the danger of rocks falling on the vehicles. Shorter grades have more gravity levels.
