Abstract
Combined with some underwater shield tunnels such as Wuhan Changjiang tunnel, the determination of reasonable cover thickness, the shield type and key parameter selection are analyzed. The key technology of stabilizing working face, preventing muddy water eruption, preventing tunnel floating, controlling shield direction, excavating long distance, abutting joint underwater, shield launching and arriving are generalized.
Keywords
underwater tunnel ; shield ; cover thickness ; type selection ; key construction technology
