dc.description.abstractA probabilistic approach to slope stability is used in this thesis to evaluate the uncertainties in the input parameters. The case study consist of a comparison between old praxis and new praxis in ground investigation methods. In the case study a road project in Norway at the Rissa area in Sør-Trønderlag is used for the study. The area is famous for the quick clay slide that occurred there in the 1978. The data used in this study is collected from ground investigations in this project. Old praxis in this study is the 54 mm piston sampler and new praxis is Sherbrooke block samples and CPTU. Stability calculation is performed in Plaxis and GEO-Suite mostly utilizing NGI-ADP model. The slope that is modelled consists mostly of clay material and therefore this study is focused on clay material. A First Order Second Moment analysis and Monte Carlo Simulation is used linked to the slope stability calculation. The method gives a probability of failure and a reliability of the calculations. It can also give answers to the impact each of the input parameter have on the result. The analysis shows that the reference value of the shear strength have the largest impact on the results. The Sherbrooke samples showed higher strength values than the 54 mm samples.eng
