Longitudinal structural deformation mechanism of shield tunnel linings considering shearing dislocation of circumferential joints

To understand the longitudinal structural deformation mechanism of shield tunnel linings, it is crucial to reasonably consider circumferential joints, especially their shearing deformation. Towards that end, first, the dislocation between lining rings caused by the differential settlement of an actual tunnel project in Shanghai was introduced in detail. Next, the longitudinal deformation model of shield tunnels derived from Timoshenko beam...
