MODERN "GEO-TECHNIQUES" EASE TRANSIT TUNNELING

The Baltimore Region Mass Transit Project has built 4-1/2 miles of tunnel, much of which is in the congested downtown area. This subway construction has involved shield tunneling, drill-and-blast, cut-and-cover, and slurry-trench walls. Linings utilized include prefabricated steel panels and precast concrete liners. Silica-based grout stabilized soil in a number of locations.
