Rolling-induced inner force in lining of DOT shield tunnel
Double-O-Tube (DOT) shield machine is more likely to roll during DOT tunnel construction and rolling correction operation is always conducted during construction. The inner force in lining will be changed during the process of rolling correction. In this paper, finite element method is adopted to analyze the inner force in lining caused by rolling correction during construction. The results indicated that it is much different between the inner forces in lining by considering rolling correction operation or not. With the rolling angle increasing, the inner force in some point increases and in some other points decrease. Therefore, the reasonable design is that the redistribution of inner force in lining during construction should be considered.
