The CivilWeb Anchored Sheet Pile Wall Design Spreadsheet also includes unique design tools which the designer can use to speed up the optimisation process. Perhaps you need to login or register.The process of anchored sheet pile wall design is typically too complex and time consuming to complete by hand, especially when the design must be optimised or several different parameters compared. This download is for Registered Users Only. The user is required to define geometry, soil data, wall data and loads. It also performs stability control checks against slipping, overturning, base pressure and displacement. It is very important to have proper drainage behind the wall as it is critical to the performance of retaining walls.ĭrainage materials will reduce or eliminate the hydrostatic pressure and will therefore greatly improve the stability of the material behind the wall, assuming that this is not a retaining wall for water. Earth pressures will push the wall forward or overturn it if not properly addressed.Īlso, any groundwater behind the wall that is not dissipated by a drainage system causes an additional horizontal hydrostatic pressure on the wall. Lateral earth pressures are typically smallest at the top of the wall and increase toward the bottom. This creates lateral earth pressure behind the wall which depends on the angle of internal friction phi and the cohesive strength c of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.

The most important consideration in proper design and installation of retaining walls is to recognize and counteract the fact that the retained material is attempting to move forward and downslope due to gravity. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures. Typically retaining walls are cantilevered from a footing extending up beyond the grade on one side and retaining a higher level grade on the opposite side.

However, the term is most often used to refer to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. The basement wall is thus one form of retaining wall. Retaining walls serve to retain the lateral pressure of soil. The total pressure or thrust may be assumed to be acting through the centroid of the triangular distribution pattern, one-third above the base of the wall. The active pressure increases on the retaining wall proportionally from zero at the upper grade level to a maximum value at the lowest depth of the wall. Description A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.
