The thermal-mechanical behavior of tunnel lining segment plays a key role in governing its fire protection design. Existing models are mainly developed for the analysis nonlinear and non-elastic behavior of segment under fire, however the complexity of the model impede their application in engineering. In this study, a multilayer analytical model is proposed to describe the behavior of segmen…
Deep buried drainage shield tunnels have the characteristics of large buried depth and high inner water pressure. The load effect of high inner water pressure and large earth pressure causes the increase of bending moment and decrease of axial force in the joint section. To meet the requirements of bearing capacity and deformation of lining structures, high stiffness segmental joints (HSSJs) wi…
