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…

In-Situ Experimental Analysis of Acceleration Response of Mountain Tunnel Lin…
Resonant rubblization technology is often utilized to rehabilitate deteriorated condrete pavements. Vibrations induced by a resonant breaker would produce detrimental effects on lining structures in tunnel during rubblization construction. The in-situ experiments were carried out in Yangjiao Mountain Tunnel in Zheijiang Province, China. First, the characteristics of rubblization-induced vibrati…
Dynamic Response of Tunnel Lining to Resonance Rubblization Induced Vibration…
The resonance rubblization technology can be adopted to reconstruct old concrete pavement and eradicate reflection cracking. This method fractures pavement into fragments quickly and directly casts asphalt on fractures, shortening time cost of reconstruction. Previous studies about this technology mainly concentrated on asphalt-casting methods, and the quality, stiffness, and flatness of reco…

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…
Experimental and Numerical Study on Longitudinal Axial Force and Deformation …
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…
