Abstract:

The shield tunnel develops towards larger diameter, deeper, longer and more complex geological conditions in China with the rapid development of urban construction. There are many tunnels bored by superlarge diameter shield had been finished. The applications of superlarge diameter shield in China are presented in terms of shield equipment, construction of internal structure, shield launching and receiving and crossing adjacent buildings; and relevant construction technologies are introduced.

Key words: shield, tunnel construction, superlarge diameter
