Three-Dimensional Analysis of the Lodalen Landslide

ABSTRACT: A convenient three-dimensional slope stability approach, presented in the accompanying paper, is applied to the analysis of the Lodalen landslide. Simple finite element stress and seepage analyses are employed to compute the three-dimensional factor of safety. The analysis shows that the three-dimensional factor of safety computed for the Lodalen landslide was 1.29 in average. The value obtained is 23 % higher than that obtained using two-dimensional solutions. The hypotheses and procedures adopted in the analyses are discussed and the validity of rigorous three-dimensional computations is evaluated
