Cantilever Walls
Cantilever walls are walls that do not have any supports and thus lead to an open unobstructed excavation.
Cantilever Excavations
Cantilever walls are walls that do not have any supports and thus lead to an open unobstructed excavation. Cantilever walls laterally restrain the retained side of the excavation by the passive resistance provided below the excavation depth. Many engineers use the cantilever wall term to actually describe gravity walls. In reality, both gravity and vertical embedded walls types can be categorized as cantilevers if no lateral bracing support is provided by means of tiebacks, struts, etc. This section examines vertical cantilever walls and the basic design methods used for cantilever wall analysis.
In general, the maximum excavation for a cantilever wall can reach up to 6m or 18ft. Deeper cantilever walls have been constructed in the past, but these require more expensive wall systems such as T-type diaphragm walls. Cantilever walls offer some advantages:
Advantages of cantilever walls:
- Cantilever walls offer an unobstructed open excavation.
- Cantilever walls do not require the installation of tiebacks below adjacent properties.
- Cantilever walls offer a simpler staged construction procedure.
