Estimation of Stability of an Unsupported Deep Vertical Cut in Clay

Dans les comptes rendus d’articles de la conférence: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: Finite element analysis was performed to simulate the excavation of an unsupported deep vertical cut (depth = 9.75 m) in clay at Welland, Ontario (Kwan 1971). For this, SIGMA/W and SLOPE/W (GeoStudio 2019 R2) were used to simulate staged excavation and to estimate its stability, respectively. To maintain the consistency of obtained results with field conditions, the simulated excavation followed the same timeline as field excavation. There was good agreement between the measured post excavation pore-water pressure contours obtained from installed field instruments with those from the numerical modelling. The numerical analysis results also showed that the failure in the cut was attributed to a tension crack, which is consistent with field observations.
