DESIGNING STEEL-FRAMED CUT-AND-COVER TUNNELS

Reinforced concrete is the material of choice when constructing cut-and-cover tunnels. The exception to this standard is when design or environmental considerations require wide, deep tunnels, which would necessitate thick walls. The solution to prohibitively thick (and expensive) concrete walls is steel-framing and reinforced concrete. This article describes the superior performance of steel-framed composite construction for cut-and-cover tunnels that are long, deep, and/or wide. Construction is outlined for a typical tunnel section and special concerns, such as field tolerances for cofferdam walls or waterproofing, are addressed. Two examples of steel-framed cut-and-cover tunnels are described: the Washington Mall tunnel (Washington, DC) and the Central Artery tunnel (Boston, MA).
