Untersuchungen mit Kernspur-Emulsionen,in shield tunneling construction. The shield machine type is different, the structure of the shaft wall starting mouth and arriving mouth is different, and the starting and arriving operations are also different. At present, many accidents of shield tunnel in China occur in the process of shield tun

Zusammenfassung der Versuchsergebnisse,tion has aroused widespread concern in the engineering field. It is worth noting that the large-diameter slurry pressurized shield faces the following risks and problems in the construction of water area (river, lake and sea) crossing the channel section: the stability control of the excavation face

https://doi.org/10.1007/978-3-322-99146-1, the corresponding construction technology is adopted to ensure the safe and efficient tunneling of shield. Due to its high permeability coefficient and low clay content, the high permeability gravel composite stratum is prone to serious mud filtration in construction, and the excavation face is difficult to form a mud film and lose stability.

,Aufbau und Einteilung der Rüttelverdichter,The construction of large diameter shield shallow overburden is one of the difficult problems in the construction process of river tunnel at present. Once something happens, the loss will be inestimable. Therefore, it is of great significance to improve and perfect the construction technology of large diameter shield shallow overburden.
