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.

Evaluation of the blocking effect of retaining walls on groundwater seepage in aquifers with different insertion depths
TL;DR: Wang et al. as mentioned in this paper investigated the blocking effect on groundwater seepage under different insertion depths of retaining wall in aquifer and found that the effective insertion depth ratio (J ) of a retaining wall of Shanghai aquifer sand is about 70%.

Effects of Principal Stress Rotation on the Cumulative Deformation of Normally Consolidated Soft Clay under Subway Traffic Loading
TL;DR: In this paper, the authors investigated the effects of principal stress rotation on the traffic load-induced settlement of subways in soft subsoil, and they showed significant increases in both excess pore-water pressure and cumulative deformation of the normally consolidated soft clay when PSR is present and simulated, and the effects become more pronounced as the maximum effective PS ratio or load frequency increases.

Ground and tunnel responses induced by partial leakage in saturated clay with anisotropic permeability
TL;DR: In this paper, a finite element analysis was conducted to study the ground and tunnel response to partial tunnel leakage coupled with anisotropic soil permeability, a novel and little-known approach that was developed from in-situ inspections of shield tunnel leakage in the Shanghai Metro system.
Journal ArticleDOI
Evaluation of train-load-induced settlement in metro tunnels
TL;DR: Based on a simplified mechanical model, the stress distribution pattern in subsoils around tunnels due to train movement is investigated in this article, where the effects of rails, connection bolts, ballast, lining and foundation are taken into account.

Ground vibration generated by a harmonic load acting on a railway track
TL;DR: In this article, a model for the propagation of vibration in the ground from a stationary oscillating load applied via a railway track structure is presented, which includes the track as an infinite layered beam structure resting on a ground made up of infinite parallel homogeneous elastic layers.

Strength of clay subjected to cyclic loading
Kenneth L. Lee,John A. Focht +1 more
TL;DR: In this paper, a survey of published data and data from private files concerning the effect of cyclic loading on the strength of clay soil is presented, showing that cyclic deterioration appears to be a strain dependent process whereby cyclic strains develop large excess pore pressures that in turn lead to softer and weaker soil.

Recompression of normally consolidated clay after cyclic loading.
Kazuya Yasuhara,Knut H. Andersen +1 more
TL;DR: In this article, a study of recompression settlements occurring in normally consolidated Drammen clay when pore pressure generated by undrained cyclic loading dissipates was presented, based on 18 stress-controlled cyclic direct simple shear tests and 6 conventional consolidation tests.
Journal ArticleDOI
Simulations of ground vibration from a moving harmonic load on a railway track
TL;DR: In this paper, a model of an oscillating load moving on a track on a layered ground is presented, which allows a visualization of the effect of the relative speeds of the load and the propagation speeds in the ground structure.
Journal ArticleDOI
A parametric study on some aspects of ground-borne vibrations due to rail traffic
TL;DR: The results of a parametric study on a three-dimensional model of ground-borne vibrations due to rail traffic are presented in this article, where the effects of train speed, train distance and ground depth are addressed.
