Analysis of interaction of prefabricated reinforced concrete tunnel with subsoil
Languages of publication
The paper presents the results of analyses of numerical interaction between a tunnel made of reinforced concrete prefabricated with backfill and stratified ground. A number of variants of foundation have been discussed: gravel cushion, on an additional concrete strip, and on a cap based on jet-grouting columns. The grounds in the simulations were described using the Coulomb-Mohr model.
