Case History of Deep Mixing Soil Stabilization for Boston Central Artery
Publication: Geotechnical Engineering for Transportation Projects
Abstract
This paper presents a case history of the deep mixing method (DMM) as it was developed and applied over a period of ten years during construction of the Boston Central Artery and Tunnel (CA/T). Deep deposits of marine clay were stabilized with DMM for large open cuts at Bird Island Flats and Fort Point Channel, both of which are described with respect to site conditions, soil properties, DMM installation and characteristics, and measured field performance. Topics addressed in this paper include water pressure distribution behind DMM walls, statistical characterization of soil-cement properties, quality control/quality assurance procedures, comparison of measured and numerically simulated deformation in clay stabilized with various configurations of soil-cement elements, and shear modulus degradation characteristics of in situ soil-cement. Recommendations are made for soil-cement properties, installation procedures, analytical modeling, design, and inspection.
