Centrifuge Model Tests and Numerical Analyses on Shallow Tunnels in Unsaturated Ground

Prof. Dr.-Ing. Wei Wu from University of Natural Resources & Life Sciences, Austria will hold a guest lecture in the framework of SFB 837 about 'Centrifuge Model Tests and Numerical Analyses on Shallow Tunnels in Unsaturated Ground'.

The face stability of shallow tunnels in partially saturated soil is investigated by means of centrifuge testing and numerical analysis. A silty soil is used in these studies. Some model tests were carried out with a geotechnical centrifuge by varying soil densities and the ground water table. FE analyses with a constitutive model were performed for partially saturated soil. In this presentation, the numerical results will be compared with the centrifuge test results.
