... * Corresponding Author s E-mail: [email protected] ABSTRACT The stability of slopes during and after excavation is always a significant issue in the field of rock mechanics. The blocky-flexural toppling failure is one of the most probable types of instabilities in rock slopes. The stability analysis of toppling...
