DESIGN OF JET GROUT FOR BASE STABILITY AND GROUNDWATER CONTROL

The East Side Access tunnel Project in New York City will connect Long Island Railroad in Queens to Grand Central Terminal in Manhattan. The Queens segment of the project comprised of cut and cover and bored tunnels. The site in Queens primarily consists of glacial deposits with cobbles and boulders with high groundwater table. Construction of a proposed approach structure in Queens includes a combination of slurry walls and jet grout plugs for base stability and groundwater control of the excavation. The plugs are made of overlapping jet grout columns. This paper presents and discuses the results of a finite element analysis carried out to better understand the interaction between jet grout columns, glacial till and slurry walls and aid the design of jet grout plugs.
