Theoretical Consideration on Statically Indeterminate Force between Slices in Fellenius' Slip Circle Method

Abstract

The slip circle method is commonly used in the stability analysis of embankment dams, earth embankments and natural slopes. But, the principal theory of the slip circle method has been not understood precisely and is often misused in the practice field. The theory of the slip circle method is reviewed strictly from the viewpoint of the theory of vector calculus and the elastic theory. The effect of statically indeterminate force on the slope stability in the Fellenius method is analyzed numerically.
