Simplified janbu method
WebbCurrently, at the University of Lausanne, I am working on two projects: the 1st is to write the algorithms for calculating the factor of safety using different slice methods in 2D (Fellenius, Simplified Bishop, Spencer’s, Janbu’s simplified, Janbu’s rigorous and Morgenstern-Price) the model can be extended from 2D to 3D once succeeded. WebbJanbu simplified method: More solutions 1) assume ∆X = 0 (no shear between slices) 2) use only Equations 1,2 and 3 (neglect moment equilibrium) 3) Good for shallow sliding …

WebbOn August 10, 2010 a series of landslides of more than 90,000 m3 occurred along the Muree-Kohala road in the northern area of Pakistan. A study was undertaken to evaluate the likely impacts of percent saturation and bulk density on mobilized shear strength along the basal rupture surface of the landslide.
