Webb15 dec. 1992 · ABSTRACT A three-dimensional (3D) analysis of bearing capacity of square and rectangular footings is presented by means of a slice method, assuming that sliding surfaces are composed of a set of log-spirals with different initial radii in the direction of the longer axis of the footing base. Discussions are first made on some fundamental … 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. http://step.ipgp.fr/images/e/e7/05_01_Limit_equilibrium_slope_stability.pdf bob jos custard wyandotte mi facebook

WebbLa méthode de Janbu simplifiée qui ne satisfait que l’équilibre des forces permet de traiter une ligne de rupture de forme quelconque (Janbu, 1973). La méthode de Spencer satisfait l’équilibre des forces ainsi que l’équilibre des moments, elle est basée à l’origine sur une rupture circulaire puis étendue au cas de rupture non circulaire (Spenser, 1967). WebbWhen studying the stability of a slope, the first issue that needs to be clarified is the slip surface, which determines the minimum safety factor. The slopes investigated here are homogenous with three distinct gradients (1:1.5; 1:1; 2:1), two defined heights (H-3 m; H-8 m), and four different soil characteristics (S1—clayey silt, S2—sandy clayey … bob joseph 21 things you may not knowWebbproposed by extending the simplified Bishop method, the simplified Janbu method and Spencers method to three dimensions.

From there on, the procedure follows WebbFor the rock masses, a simple compression test was performed. As for the physical properties, a specific gravity test of solids was carried out in accordance with ASTM D854-58. The geomechanical classification of the rock masses was carried out according to RMR, SMR, Q and GSI, thus allowing the characterization of the slopes and the …
