Numerical analysis of the colapse of an Nicoll Highway excavation in Singapore
Fabianová, Klára ; Mašín, David (advisor) ; Hrubešová, Eva (referee)
The diploma thesis dealt with collapse of deep excavation which occurred 20th April 2004 in the souhteast part of Singapore. The collapse of temporary retaining system was caused mainly by incorrect setting of Mohr-Coulomb material model in software called Plaxis. The collapse is analyzed by hypoplastic model for clays in this thesis. Hypoplastic model can simulate better behaviour of two main layers of local profile which are marine clay. The simulation of collapse of deep excavation, done by hypoplastic model, was realized in Plaxis software. The results were compared with measurement of inclinometers and also with simulation in witch Mohr-Coulomb model was used. Predictions of hypoplastic model mostly overestimate deformation of diaphragm walls of the excavation and results of Mohr-Coulomb model are very similar. It seems that final predictions of hypoplastic model are influenced mostly by strength than by nonlinearity of stiffness.
