Question: 1 / 400

What is the angle of repose?

The angle of the spoil pile to the ground

The angle of repose refers to the steepest angle at which a sloped surface, like a pile of loose material or spoil, can remain stable without sliding. This concept is crucial in various fields like civil engineering, mining, and construction, as it helps determine the safety and stability of materials piled up. When considering a spoil pile, the angle of repose is specifically the angle formed between the horizontal ground and the slope of the pile itself. This angle is influenced by the material's properties, such as size, shape, and moisture content, and is important for ensuring that heaps of soil or other materials do not collapse or shift unexpectedly, which could create hazards on a work site. Understanding this angle helps operators manage piles safely and effectively.
