Limit equilibrium is an analysis methods where limit state conditions are assumed. For excavations and earth retaining structures this usually means that earth pressures are assumed on both the retained and excavated sides. These pressures may represent a failure state such as active or passive lateral earth pressures, or an assumed redistribution such as diagrams by Peck or FHWA.
The retaining wall is then analyzed to provide moment and force equilibrium, when possible. Support reactions are also calculated, typically by using the tributary area method.
The following examples demonstrate some of the limit equilibrium analysis methods included in DeepEX.
DeepEX is the Ultimate software for design of deep excavations. It incorporates general limit equilibrium methods and non-linear analysis method with use of elastoplastic Wincler springs.
DeepEX does both structural and geotechnical analysis of any deep excavation wall and support system.
Additional, optional modules are available and can make your life easier!
