ASSESSMENT OF THE STRESS-STRAIN STATE OF RETAINING WALLS OF DEEP PIT IN CONDITIONS OF DENSE URBAN CONSTRUCTION

The comparison of the results of geodetic monitoring of displacements of existing buildings and retaining walls construction and numerical simulation of the stress-strain state of the system ‘soil – retaining walls – existing buildings’ is shown. The back analysis was performed and the parameters of the soil model were verified. It is recommended to verify the soil model parameters on the basis of laboratory tests of soil parameters in a wide range of loading/unloading using axial and triaxial soil compression.
