Abstract

The Central Artery/Tunnel (CA/T) Project also known as "Big Dig" has been the largest public work ever attempted in the American history. The selection of an appropriate earth retaining system for elimination of ground movement and preservation of adjacent structures was a key constructability challenge for construction practitioners at the CA/T. This paper explains the critical factors which had an effect on the selection of the Soldier Pile-Tremie Concrete (SPTC) slurry walls at the project. The advantageous of this system has been illustrated for other projects that face similar challenging conditions.
