Analysis of ground settlement caused by tunnel construction
Article (Published version)
MetadataShow full item record
Prediction of ground settlement is considered as highly significant in the design of tunnels located in urban areas. 2D and 3D modelling of tunnel construction, as needed for settlement analysis, is made according to the finite-element method. The ground settlement profiles, obtained during simulation of the small-depth openface tunnel excavation in clayey-marly terrain, are presented. Settlement cross sections obtained by 2D and 3D analyses are compared.
