block-flexure is the most common mode of toppling failure in natural and excavated rock slopes. in such failure, some rock blocks break due to tensile stresses and some overturn under their own weights and then all of them topple together. in this paper, first, a brief review of previous studies on toppling failures is presented. then, the physical and mechanical properties of experimental mode...

In layered and blocky rock slopes, toppling failure is a common mode of instability that may occur in mining engineering. If this type of slope failure occurs as a consequence of another type of failure, it is referred to as the secondary toppling failure. “Slide-head-toppling” is a type of secondary toppling failures, where the upper part of the slope is toppled as a consequence of a semi-circ...

One of the most conventional toppling instabilities is the block-flexural toppling failure that occurs in civil and mining engineering projects. In this kind of failure, some rock columns are broken due to tensile bending stresses, and the others are overturned due to their weights, and finally, all of the blocks topple together. A specific feature of spheroidal weathering is the rounding of th...

toppling failure is one of the most common modes of failure of rock slopes in layered rock strata. flexural toppling is one of the well-known modes of the failure. this type of failure occurs due to bending stress. in this article, a brief yet comprehensive review of toppling failure is presented. firstly, the conditions and general mechanism of the failure are described. then, experimental, th...

This paper demonstrates the ability of Shear Strength Reduction (SSR) analysis based on the Finite Element Method (FEM) to model the scale effects of discontinuity networks on the stability and failure mechanisms of slopes in blocky rock masses. Through three examples, it shows how these mechanisms depend on joint network geometry and change with increasing slope height. Introduction Scale Effe...

One of the most important instabilities of rock slopes is toppling failure. Among the types of toppling failure, block-flexural failures are more common instability which occurs in nature. In this failure, some rock blocks break because of tensile stresses, and some overturn under their weights, and next to all of them topple together. Physical and theoretical modeling of this failure is studie...

Underground mining activity in the karst mountain southwestern China has induced several large-scale rocky landslides and caused serious casualties. At present, there is a lack of systematic research on formation mechanism this area using multi-method fusion technology. First, orthophoto images landslide obtained by UAV photography were used to analyze deformation characteristics landslide. Sec...
