Groundwater Control in Tunneling. Volume 2: Preventing Groundwater Intrusion Into Completed Transportation Tunnels

摘要

This is the second volume of a three-volume report. This Volume 2 describes various groundwater control methods for keeping tunnels dry during the life of the structure. The methods discussed include means employed to provide impervious structural concrete, types of waterproofing membranes, methods used to seal segmented tunnel linings, grouting of soils and rock, and sealing sunken tube tunnels. Problems resulting from inadequate methods or failure of control measures are discussed as well as maintenance programs to maintain the integrity of various groundwater control systems.
