... method). 3.1 Simulation by dynamic limit equilibrium method Deformation of rock slope occurs by slip of the fail- ure surface. Therefore, the dynamic limit equilibrium method was used to simulate the slip of the model slope on the failure surface. A mechanical model of slip develops by equilibrium...

.... The failure surface developed within a mélange formation during a rainy season and resulted in buckling of the road by about 2 m. Different limiting equilibrium methods and discrete finite element methods (DFEM) were used for the assessment of the slope instability. The factor of safety of the slope changes...

.... The geometry of the failure surface is determined using calculus of variations. The effect of the strength parameters and the overburden on safety against uplift are studied using the derived solution. It is shown that uplift pressure increases significantly with the uniaxial compressive strength of the rock...

Therefore, in this study a numerically simulation of laboratory tests, namely uniaxial and triaxial compression, direct shear, and Brazilian tests were conducted on heterogeneous SRSM and homogenous specimens. The results showed that instead of an individual and sharp failure surface, multiple...
