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 ...
This process is repeated with successive layers of panels, earth and reinforcements. The panels are thus tied into the earth embankment to make a stable structure with balanced stresses. [82] Although construction using the basic principles of MSE has a long history, MSE was developed in its current form in the 1960s.
Heavy construction equipment is usually used due to the amounts of material to be moved — up to millions of cubic metres. Earthwork construction was revolutionized by the development of the scraper and other earth-moving machines such as the loader, the dump truck, the grader, the bulldozer, the backhoe, and the dragline excavator.
The main problem is the space required to construct and maintain such a structure. A flood embankment of 2.5 metres high requires an outreach of 15 metres, which makes it unsuitable in some areas.
Hydraulic fill is likely to be the most economic method of construction. Even when the source material lacks sufficient elevation, it can be elevated to the sluice by a dredge pump. In the construction of a hydraulic fill dam, the edges of the dam are defined by low embankments or dykes which are built upward as the fill progresses. The sluices ...
Ash ponds are generally formed using a ring embankment to enclose the disposal site. The embankments are designed using similar design parameters as embankment dams, including zoned construction with clay cores. The design process is primarily focused on handling seepage and ensuring slope stability.
Embankment dam, a dam made of mounded earth and rock; Land reclamation along river banks, usually marked by roads and walkways running along it, parallel to the river, as in: The Thames Embankment along the north side of the Thames River in London, England The Victoria Embankment contained within the Thames Embankments

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 ...
