Journal ArticleDOI
Long-term settlement behaviour of metro tunnels in the soft deposits of Shanghai
TL;DR: In this paper, the authors show that tunnel deformation is mainly due to urbanisation-induced land subsidence in Shanghai, and the magnitude of tunnel settlement is correlated to sublayer settlement rather than ground surface settlement.
Journal ArticleDOI
Longitudinal structural modelling of shield tunnels considering shearing dislocation between segmental rings
TL;DR: In this paper, the authors proposed a new longitudinal structural model to consider the shearing dislocation between rings, which can describe the actual deformation mode of a tunnel reasonably and compared with the traditional Euler-Bernoulli beam model based on a field measured longitudinal deformation of a Shanghai metro tunnel.
Journal ArticleDOI
Laboratory evaluation on the effectiveness of polypropylene fibers on the strength of fiber-reinforced and cement-stabilized Shanghai soft clay
TL;DR: In this paper, a laboratory evaluation on the strength behavior of cement-clay admixture improved by polypropylene fiber is presented, and the results show that fiber additive can significantly improve the strength and ductility of the cement treated Shanghai clay.
Journal ArticleDOI
Prediction of maximum surface settlement caused by earth pressure balance (EPB) shield tunneling with ANN methods
TL;DR: A modified index that defines the physical significance of the input parameters was proposed to quantify the geological parameters, which improves the prediction accuracy of ANN models and found the GRNN model to outperform the BP and RBF neural networks in terms of accuracy and computational time.
Journal ArticleDOI
Soil-tunnel interaction modelling for shield tunnels considering shearing dislocation in longitudinal joints
TL;DR: In this paper, a soil-tunnel interaction model based on the Timoshenko beam simplified model (TBSM) of tunnel on Vlasov foundation was proposed to analyze the behaviors of a shield tunnel subjected to external forces transferred from surcharge load on the ground surface.
