Abstract

Abstract:

The shield often has to pass through stations and ventilation tunnels in the construction of Metro shieldbored tunnels. There is great difficulty for construction organization and construction technology. The construction organization and technical difficulties and countermeasures of local semiring assembly shield passing through intermediate ventilation tunnel are analyzed. The paper can provide references for similar projects in the future.

Key words: tunnel, local semiring assembling, intermediate ventilation tunnel
