Abstract
The Metropolitan Atlanta Rapid Transit Authority combined three new technologies − microtunneling, jet grouting, and rock-socketed "minipiles" − to successfully construct twin rail tunnels under an eight-lane highway with as little as 4-1/2 feet of cover. Geotechnical parameters, tunneling method selection, and construction methods are discussed. Ground response and monitoring are summarized.
