An embankment is a raised wall, bank or mound made of earth or stones, that are used to hold back water or carry a roadway. A road , railway line , or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain , the alternatives being either to have an ...

In earthmoving , cut and fill is the process of constructing a railway , road or canal whereby the amount of material from cuts roughly matches the amount of fill ...

A rockfall protection embankment is an earthwork built in elevation with respect to the ground to intercept falling rock fragments before elements at risk such as roads and buildings are reached. This term is widely used in the rockfall community but the terms bunds and walls are sometimes used as alternatives.
Cuts are typically used in road, rail, and canal construction to reduce a route's length and grade. Cut and fill construction uses the spoils from cuts to fill in defiles to create straight routes at steady grades cost-effectively. Cuts are used as alternatives to indirect routes, embankments, or viaducts.
If the value of factor of safety is less than 1.0, the slope is unstable. All limit equilibrium methods assume that the shear strengths of the materials along the potential failure surface are governed by linear (Mohr-Coulomb) or non-linear relationships between shear strength and the normal stress on the failure surface.

Bricks remain in common use. They are small and easy to handle, strong in compression, durable and low maintenance. They can be formed into complex shapes, providing ample opportunity for the construction of aesthetic designs. The four basic types of structure are residential, institutional and commercial, industrial, and infrastructure/heavy. [1]
