Support Systems for Deep Excavations

The role of support systems is to provide lateral bracing for retaining walls. Support systems can be subdivided into external and internal depending on the load transfer mechanism. External supports (namely tiebacks) work by transferring lateral excavation loads beyond the active zone of soil movements (retained side). On the other hand, internal supports such as struts, rakers, or floor slabs, transfer lateral loads within the excavation (across opposing walls or to other internal structures). In all cases, support and retaining systems have to work closely together in order to guarantee a high level of performance.
