Abstract

Abstract:

The shield should be transported to launching shaft in tunnel after dismantling when the receiving shaft has been closed. As a result, a series of shield dismantling methods for 6 390 mm EPB shield used in Line No. 6 of Tianjin Metro, including cutterhead dismantling, front shield dismantling, shield body dismantling and shield tail dismantling, are designed and applied; and the shield transport in tunnel can be achieved. The abovementioned shield dismantling methods can provide reference and guidance for similar projects in the future.

Key words: earth pressure balance (EPB) shield, shield dismantling method, closed station, shield receiving
