Sustainable Slope Stability Analysis: A Critical Study on Methods

When studying the stability of a slope, first issue that needs to be clarified is slip surface, which determines 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 S3—sandy silty clay, S4—clay). purpose this paper develop new methodology capable estimating factor shape centre critical delivering an improved estimate slope probability failure, can represent significant component in more precise risk assessment. This compares methods used analysis, examining their hypotheses effects on estimated surface. study limit equilibrium results those determined by shear strength reduction method using approach based upper-bound analysis compare predictions extracted from these finite element (FEM) analysis. discretizes mass into elements. Hence, it establishes kinematically admissible velocity field searching for failure mechanism slope. Results FEM show influence geometry mesh size density In study, plots regression curves five surface shapes, including circular (benchmark), depends material Furthermore, they layout logarithmic spiral, damped sinusoid, parabola, etc.; not always circular. reveals none approaches consider all uncertainties concerning interpretations surfaces.
