GROUND CONTROL

摘要

THE USE OF GROUND freezing to provide excavation support and groundwater control for the construction of cross passages between two tunnels has been used extensively in Europe, Asia and most recently in North America on the Port of Miami Tunnel and the Northgate Link Extension in Seattle. There are more projects in the planning phase in the United Kingdom, Los Angeles and Australia where ground freezing is being considered as the most technically appropriate method of ground improvement.
