Retaining Systems for Deep Excavations
The term "Retaining System" for a deep excavation refers
to the structural system that retains soil and water and prevents
it from collapsing into the open cut. Many types of retaining
systems exist. The selection of the proper retaining system depends
on a wide range of factory such as: Economical, soil conditions,
protection of adjacent structures, ease of construction, environmental
issues and more. Typical retaining systems include soldier pile
and lagging, sheet piling, secant pile or tangent pile walls,
soil mix walls, and diaphragm walls (also known as slurry walls
in the U.S.).
