盾构衬砌管片的壳–弹簧设计模型研究

Studies on shell-spring design model for segment of shield tunnels

围绕盾构衬砌管片的设计模型问题,提出了一种新的壳–弹簧设计模型,详细论述了模型的建立过程。运用壳–弹簧模型与梁–弹簧模型分别对衬砌管片通缝和错缝拼装进行对比分析,比较分析了衬砌管片错缝拼装下两种模型计算结果的异同,对盾构管片的设计具有一定的指导作用。

The design model of shield segment was discussed, and a new shell-spring design model was put forward. The establishing process of model was also discussed in detail, and shell-spring model and beam-spring models were used to analyze the tunnel with sequential and staggered segment seams. The calculated results with these two models were compared.
