| Abstract:According to the comprehensive problem of large slope and small radius curve in the construction of a shield interval of Tianjin metro line 3, by the use of variety of data accumulated in the construction process, with the stress analysis and mathematical statistics, the analysis is made on the influence of the variety of data to shield tunneling, and the discussion is made on the shield tunneling operation and rectification technology. It is realized that the correct analysis on the thrust force and direction, the articulated structure and correction curve setting in the special curve segment is the focus for shield operation and rectification in large slope and small radius curve segment. |
