SLURRY WALLS SUCCEED IN BOSTON

The use of slurry walls as permanent load-bearing elements could get a big boost in the U. S. from the Massachusetts Bay Transportation Authority's (MBTA) experience in building a 3.2-mile subway extension. More than 600,000 sq ft of slurry wall has been installed to hold platforms and roofs in three of the four new stations at the Cambridge end of the Boston area transit system's Red Line. The $574-million project claims a U. S. record - 14,800 lin ft of continuous slurry trench wall in a cut-and-cover tunnel. The slurry trench walls are in a variety of soils, including glacial till and rock, mixed face granular material and soft clay. A Federal Highway Administration test program indicates that the construction has worked well.
