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...

Online Multidimensional Time Series Anomaly Detection Algorithm based on Shield Construction
Abstract: The real-time anomaly detection is very important in the process of shield tunneling. The alarm for abnormal events can help the staff to make decisions quickly and ensure the engineering safety. However, the traditional methods of shield anomaly detection are mainly depended on analysing for one-dimensional time series one by one, so its accuracy is low, which cannot meet the actual...
