This book systematically introduces the new technology used in the construction of underwater large slurry shields under complex conditions. The basic principles, scope of application, construction technology and technical points of the key technologies such as the origin and arrival of the shield, crossing the shallow soil in the middle of the river, crossing the guard, and changing the knife and opening the knife are clarified.

Combines with typical domestic engineering cases, not just relying on technical research and theoretical analysis Introduces Large Diameter Shield Origination and Arrival Technology fin detail Analyses key technologies of large diameter shield tunneling in shallow soil cover and through the embankment
