Design Of Caisson Wall Systems

Caisson walls or secant pile walls consist of intersecting drilled shafts where typically soldier piles (W steel sections) are placed inside a drilled shaft, typically not every shaft has a soldier pile.  This type of excavation support is a stiffer system than soldier pile and lagging so it is commonly the choice of excavation support near an existing building or sensitive structures.  Caisson walls are also used next to high water tables as they typically provide a water tight support. These walls employ the same lateral supports as soldier piles & lagging systems: soil tiebacks, rock tiebacks, corner braces, struts, rakers and/or dead man anchors.
