| Abstract: | Segment misplacement staggering is one of the common quality defects in shield construction.Serious staggering will lead to large area damage and leakage of the formed tunnel,which not only affects the safe operation of the train,but also seriously affects the safety and durability of the tunnel.Based on the background of large-scale damage of lining segments in a shield construction section of Xi'an metro,this paper analyzes the causes and mechanism of segment dislocation,and puts forward corresponding technical control measures. |
