A new method for structural health evaluation of shield tunnel
Abstract: This study presents a new method for evaluating structural health with shield tunnels. As a fuzzy system, evaluation of tunnel health has the characteristics of randomness and fuzziness. Traditional tunnel health evaluation methodologies do not account for the fuzziness and randomness of the system. Therefore, using cloud theory, this study puts forward a new the method for evaluating tunnel...

Numerical Modelling of Bolt Corrosion Impact on Performance of Segmental Shield Tunnel Lining
Abstract: Bolt corrosion has been encountered more often for tunnels embedded under water or in saturated soils with the tunnel operation time. The corrosion of tunnel bolts will definitely reduce the rigidity and ultimate bearing capacity of tunnel lining, increase the deformation of the tunnel convergence, and thus endanger the safety of the tunnel structure. In this paper, the Shanghai metro tunnel...

Robust Design Method of Large-diameter Shield Tunnels through Multiple Strata
Abstract: Since the large-diameter shield tunnel usually goes through multiple strata, the variation of ground condition may have a very significant impact on the tunnel performance. Unfortunately, the conventional design method cannot consider the effect of uncertainty of the multiple strata. Thus, the robustness design method of large-diameter shield tunnelling through multiple strata is proposed. The...
