Design Of Soldier Pile And Lagging Systems

Soldier pile and lagging consists typically of W steel sections (soldier piles) placed inside a drilled shaft, that are installed prior to excavation. As the excavation takes place the wood lagging is installed between soldier piles. Lateral supports for soldier pile and lagging include: soil tiebacks, rock tiebacks, corner braces, struts, rakers and/or dead man.
