Abstract

Abstract: Distribution of the lifting points, bearing of the lifting points and local stress of clinging structure are analyzed, the disassembly method is determined and the disassembly process is described during the disassembly of the main bearings of 2 shield machines in Shiziyang Subsea tunnel. The paper can provide reference for the disassembly of the main bearing of the shield machine of similar projects in the future.

Key words: Siziyang tunnel, shield machine, main bearing, lifting point, local stress
