COMPUTER ALGORITHM FOR SLIP-CIRCLE ANALYSIS

This paper presents a computer algorithm for examining the stability of slopes by slip-circle analysis. Examining stability by slip-circle analysis is carried out by examining the equilibrium of the potential sliding mass, infinite slices, and is solely based on limiting equilibrium. The analysis satisfies both force and moment equilibrium conditions. The analysis is applicable for cases with tension cracks, and also it takes into account any known variation of pore-pressure coefficient within the potential sliding mass. The computational algorithm presented here yields rapid numerical solution. The analysis of each slip-circle takes about two to three seconds on the icl 1909 series computer. Further, the analysis can be conveniently extended for analysing the slope section with continuously varying soil strength parameters with the potential sliding mass. (Author/TRRL)
