The process of analysis takes place though the application of the principles of geology, hydrology, soil properties, and physics. Click here for an excellent example of slope stability analysis. There are several main solutions for stabilizing and unstable slope. Two views of a landslide area in southwest Montana before and after supports were added to the road above the slide area and the slide area was graded to reduce risk of future mass wasting. Buttressing To counter the driving forces of a slope, buttresses can be used to increase the resisting force.
Drainage reduces the seepage forces on a slope as well as erosion.
Reinforcement Slopes can be reinforced by adding strengthening elements. Methods include the use of soil nailing and stone columns. When a cut or fill is required and there is not enough space available for just the slope itself, a retaining wall is commonly used for slope stabilization. Retaining wall with drainage pipes protects the road. The use of grass, shrubs, and trees is highly effective for soil stabilization purposes.
