Develop correlations between soil parameters: Jandola Pakistan landslide as case study

Abstract

The focus of this research is on comparing the slope factor of safety determined from computer modelling of basic slopes using frequently used limit equilibrium methods with that using less typically used finite-element methods. Several various slope geometry and material property combinations are used in the comparison study. The main objective of this research is to develop useful correlations for slope stability analysis projects. Useful correlations are developed under seismic and non-seismic conditions. Factor of safety is correlated with shear strength and shear stresses. It is found that the seismic and non-seismic factor of safety values are correlated at 99.6% applicability. Shear strength and shear stress are correlated with the non-seismic factor of safety at 99.5% applicability. Similarly, shear strength and shear stress are correlated with the seismic factor of safety at 100% applicability value. The non-seismic slope factor of safety in the case of limit equilibrium analysis is correlated with the non-seismic factor of safety in the case of finite-element analysis at 83.8% applicability. The Jandola landslide is considered as a case study to cross-check the correctness of the developed correlations. These correlations can be used in slope stability analysis projects.
