What is slope stabilization?

What is slope stabilization?

Slope stabilization refers to any implemented technique that aims to stabilize an unstable or inadequately stable slope. The purpose of slope stabilization techniques is to increase the Factor of Safety of a slope to a level that is considered adequate.

How do you monitor slope stability?

Some techniques have been introduced to monitor the stability of slopes, such as the global positioning system (GPS), the geographic information system (GIS), aerial photography, and inclinometers. Each one of these offers advantages against others, but at the same time also possesses different limitations.

Why is slope stabilization important?

Slope stability is considered as the basic requirements of any road that are built on inclined plane. The purpose of the slope stabilization is to prevent the rain impact, run off velocity of the road and also the soil erosion.

Why is slope monitoring important?

Monitoring of the slopes of surface mines can prevent loss of life, equipment, production and possibly the loss of the mine. The effectiveness of such monitoring depends on the extent to which slopes give adequate advanced warning before failing, and on the ability of the monitoring system to detect such warning.

Why do we use slope monitoring?

Slope monitoring are involves an important role in the risk management of large open pit slopes. It has used for slope stability radar (SSR), ground field control point by GPS or total station, visual observations and other geotechnical instrument form a key component of modern open pit slope management programs.

What are the different types of slope?

Slopes come in 4 different types: negative, positive, zero, and undefined. as x increases. The slope of a line can also be interpreted as the “average rate of change”.

What are the 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.

Why is stability important in engineering?

This information matters to civil and geotechnical engineers involved in planning construction for roads, dams, embankments, and other excavated slopes, as failing to understand slope stability could result in landslides, unwanted movement, or injury to both property and individuals.

How does slope stability radar work?

The slope stability radar has been developed to remotely scan a rock slope to continuously monitor the spatial deformation of the face. Using differential radar interferometry, the system can detect deformation movements of a rough wall with sub-millimeter accuracy, and with high spatial and temporal resolution.

What is factor of safety in slope stability?

The slope stability safety factor refers to the ratio of the soil shear strength to the shear stress of a possible sliding surface in the slope.

What causes slope instability?

A slope can become unstable if fractures at the top of a slope are filled with water. The pressure created due to water in the fractures loads the soil and increases the shear stresses.

Why should slope stability monitoring be done?

Slope monitoring instruments are designed to aid in achieving the best possible production by knowing how and when to mine certain benches and not prevent equipment from accessing areas planned for mining. In addition, the relaying of false information that may cause an area to be quarantined must be avoided.
