Most of the traditional design methods assumed shield tunnel lining as a perfectly formed
ring, without special attention to the effect of pre-deformations and inaccuracies produced in …

Lining safety can be threatened more severely at the construction stage than at the service
stage, because the loads at the construction stage are larger. This study presents an in-situ …

Based on loading analysis of shield tunnel segments during the assembly phase, a finite
difference model is established for segmental lining structure in assembly stage. The …

Recently, the double-layer lining of shield tunnels has begun to be applied as a new form.
However, due to the lack of the related researches, the key parameters of the double-layer …

An analytical solution for the calculation of internal forces of a jointed segmental precast
DOT (Double-O-Tube) lining based on the unbalanced forces transition method was …

Numerical simulation analysis method is empoyed to study the mechanical behaviors of
segments of connecting passage of a shield tunnel. The general construction method and …

It is known that the local joint behavior has a significant influence on the overall performance
of the lining structure. However, few direct experimental investigations focus on their …

In the field of shield tunnels, the occurrence of uneven longitudinal settlement in segment
linings has presented persistent challenges, including heightened risks of localized damage …

Through the analysis of the sensitive factors of effective bending rigidity ratios of shield
tunnel structure, an efficient solution method based on prototype tests is proposed for the …

To simulate the failure mechanism of tunnel segmental lining joints and longitudinal bolts
under uneven longitudinal ground settlement, a numerical model with 3D lining rings and …
