Excavation Supported by Diaphragm Walls – Inclinometric Monitoring and Numerical Simulations

The results of the numerical simulation of deep excavation supported by a diaphragm walls are presented. Mohr-Coulomb and Hardening Soil models were used. The obtained horizontal displacements are compared with the results of the inclinometric monitoring and the observed discrepancies are discussed. Movement of the bottom of the wall – which is often neglected – is clearly observed both in the numerical simulations and in-situ measurements.
