摘要
Abstract
Taking the secondary lining for tunnel of Φ4 700 mm in the No. 13 bid-section for the South Main Canal--an assistant project in Beijing for the South-to-North Water Transfer Project as an engineering case, the construction method for the whole-circle and one-time pouring of self-compacting concrete for the secondary lining inside of the shield-excavated tunnel is de-cribed herein; in which the impacts from both the self properties and the in situ pouring technology of the self-compacting concrete on the surface quality of the secondary lining of the tunnel is dissertated, and then the relevant countermeasures for how to reduce the conventional defects of the surface quality are summarized as well.关键词
