Modeling of rock slopes against flexural toppling failure in static and dynamic conditions (Physical, numerical and analytical methods)

Abstract

Flexural toppling is a mode of failure that may occur in a wide range of layered rock strata in excavated and natural rock slopes. The failure occurs due to bending stresses. In the research, first, the failure modeled in laboratory in static and dynamic condition with tilting machine and shaking table, respectively. Next, the physical modeling analyzed with numerical method in UDEC-DM software. Finally, the results of physical and numerical modeling compared with existing analytical approach outcomes. The comparisons showed that UDEC-DM is suitable for analysis of the failure.
