Three-Dimensional Seepage Flow Analysis of Slurry Shield with Permeable Filte…
The filter cake on the tunnel face has a significant influence on project of the slurry-driven shield. During the excavation, only permeable filter cake is allowed to form because the rotating speed of cutter wheel is fast. Through the filter cake, the water of slurry will infiltrate into the soil. The water enhances the hydraulic head and the risk the failure of tunnel face. In order to determ…
A Multilayer Analytical Model and Experimental Verification for Tunnel Lining…
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…
Numerical Study on High Stiffness Segmental Joints of Shield Tunnels
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…

Numerical Investigation on the Mechanical Characteristics of a Special-Shaped…
A shell-spring finite element model of a special-shaped tunnel was established to investigate the distribution of internal forces and deformation mode of the lining at the designed buried depth. The numerical results were compared with prototype loading test results and uniform beam model, which showed that the shell-spring model can be an optimal model to calibrate the 3D distribution of the i…
