Abstract

This study presents a theoretical framework for monitoring the stability of a slope in an efficient and cost-effective manner. The optimal arrangement of monitoring points is achieved using strength reduction finite element analysis and redundancy optimization analysis. Using a highway slope in South China as a case study, it demonstrates that the developed theoretical framework has the capability of designing the three-dimensional distribution of the monitoring points within the slope in an optimal way. In addition, it shows that, with the increase of the reduction coefficient, the plastic zone inside the slope gradually expands with the decrease in the shear strength of the soil. Furthermo..
