Deep Excavation Wall Systems

Retaining Wall Types for Deep Excavations

he 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 retaining system options are available. The selection of the proper retaining system depends on a wide range of factors 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.).

Excavation Wall Types and Software

An advanced software like  DeepEX - Shoring Design Software is usually required for the analysis and design of different wall types. I In our program the wall sections can be easily created through user-friendly dialogs. The user can define all section properties and select the structural sections of rebars and steel beams through extensive implemented section databases. The software advanced design capabilities allow the fast evaluation of different alternatives, leading to safe and economic solutions.

Below you can access and review information about the most common wall types used in retaining walls.
