Analysis of ground surface settlement due to shallow shield tunnels
International Journal for Numerical and Analytical Methods in Geomechanics, 1977When shallow tunnels are constructed under streets and buildings, surface settlement due to the tunnelling and its control becomes essential to prevent any environmental problems. This paper deals with finite element analysis and a simplified numerical method for computing the surface settlement due to tunnelling. The computed results are compared with

Evaluation of wall deflections and ground surface settlements in deep excavations
Arabian Journal of Geosciences, 2014A study to illustrate the ground surface and wall movements due to excavation is undertaken based on two-dimensional nonlinear finite element (FE) modeling and analysis. The FE model and nonlinear solution strategy are built in the open-source software platform, OpenSees, of the Pacific Earthquake Engineering Research Center.

Tunnelling and Underground Space Technology, 2019
Soft soil poses more challenges to the construction of large-diameter shallow-buried tunnels than other soils: the surrounding rock mass is more easily disturbed, and the tunnel stability is more influenced by various factors.

Ground Surface Settlements due to Underground Works
2007Ground surface deformations due to tunneling are crucial in urban regions where damages to surface structures and utilities should be prevented. In this paper the detection and monitoring of the vertical displacements of an area situated above the axis of one of the Athens METRO tunnels, where damages on constructions were observed during the ...

Numerical Analyses on Wall Deflections and Ground Surface Settlements in Excavations
AIJR Proceedings, 2022Ground movements may cause damages to structures. Accurate estimations of ground movements are therefore essential for the risk assessment programs for projects involving underground constructions. Presented herein is a study on the influence of various parameters on the magnitudes and the distributions of ground movements during deep excavations with ...

A method of estimating surface settlement above tunnels constructed in soft ground
Canadian Geotechnical Journal, 1983A technique suitable for the analysis of lined tunnels constructed in soft soil is described. This technique permits consideration of the soil-lining interaction, lining weight, and plastic failure within the soil. Particular attention is given to the simulation of loss of ground including the annular void created by the difference between the ...

Prediction on Ground Surface Settlement Caused by Subway Shield Construction in Xi'an
Applied Mechanics and Materials, 2013In order to study the ground surface settlement induced by shield tunneling, on the background of Xi'an metro line 2, this paper made use of the measured ground surface settlement to conduct characteristic parameters fitting of the settlement trough by Peck formula and the modified stiffness approach, proposed the initial suggestive value of the ...
