AbstractInfluence factors of the tunnel second lining concrete appearance quality was investigated by the

QC activity group, the results showed that poor control of concrete pouring and second lining trolley was the main problems. The corresponding solutions to solve these problems such as improper treatment of construction joint and edge joint in the structure concrete constructionserious deformation of lastometer screw, concrete distribution and improper vibration were proposedwhich improved the concrete structure engineering quality and achieved better quality benefit and social benefit.
