The deformation and stress of a super-large-diameter shield tailskin are analyzed in this paper. Four kinds of structure analysis models, i.e. the perfect solid shell model, the defected solid shell model, the perfect hollow-layered shell model, and the defected hollow-layered shell model are formed to study the effects of initial geometrical defects and the hollow-layered shell formation on th…

50 MW heat release rate fire is the most representative in tunnel fire. The paper has a systematic study on the temperature distribution and thermal damage of the maximum temperature section with a heat release of 50 MW by means of theoretical analysis, numerical simulation and experimental investigations. Research results show that with the increase of ventilation velocity, the maximum tempe…

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…
Dislocation between adjacent rings and opening of conferential joints are two typical distress of shield tunnel due to longitudinal uneven settlement. However, most existing analysis methods only considered one distress. In this study, a longitudinal deformation model of shield tunnel is proposed based on the longitudinal deformation mechanism, which takes both bending deformation and shear def…
