Abstract Dislocation of segments in shield tunnels significantly contributes to joint leakage. making it crucial to identify the critical dislocation amount of segment linings. To explore the waterproofing mechanism of sealing gaskets under water pressure. a structural coupling finite element analysis model was created. https://www.diegojavierfares.com/mega-pick-SA439-EF75-5-x-7-Embroidery-Machine-Hoop-mega-pick/
