Abstract

Artificial ground freezing converts soil pore water to ice. The resulting frozen ground is relatively strong and impervious. It has been used in many geotechnical engineering applications, especially difficult and unusual construction projects. Its applications have been widely used in temporary excavation supports for deep circular shaft construction. Recently, its applications have expanded to provide temporary support for deep open cut excavations and ground stabilization for tunneling. This paper describes artificial ground freezing technology, discusses its engineering properties, illustrates its applications in geotechnical engineering, and concludes with a brief summary of various artificial ground freezing project experiences. Design and performance of the frozen ground will be compared for frozen soil tunnels and a cantilever wall.

Artificial Ground Freezing in Geotechnical Engineering

Arlington, Virginia

Artificial ground freezing converts soil pore water to ice. The resulting frozen ground is relatively strong and impervious. It has been used in many geotechnical engineering applications, especially difficult and unusual construction projects. Its applications have been widely used in temporary excavation supports for deep circular shaft construction. Recently, its applications have expanded to provide temporary support for deep open cut excavations and ground stabilization for tunneling. This paper describes artificial ground freezing technology, discusses its engineering properties, illustrates its applications in geotechnical engineering, and concludes with a brief summary of various artificial ground freezing project experiences. Design and performance of the frozen ground will be compared for frozen soil tunnels and a cantilever wall.
