The study has presented a sensitivity analysis of a rock mass prone to toppling due to the
variation of the strength parameters. The data from the Lornex pit at the Highland Valley …

This paper studies the failure mechanism of block-flexural toppling by using physical
modelling test. Base friction apparatus was used in this study. The specimens were made by …

In toppling of rock slopes, thin slabs of rock displace out of the slope, eventually forming a
rupture surface. This toppling process involves slip between the thin slabs and tensile …

This study is primarily a numerical investigation into the geomechanical response and
deformation of two kinds of rock materials, massive and jointed rocks to excavation. Two …

ABSTRACT ABSTRACT The failure of any particular rock slope can involve a number of
modes including planar sliding, circular sliding, wedge failure, toppling and some …

Toppling failure occurs by tensile stress caused by moment due to weight of rock columns.
Since the geostructural weaknesses (natural microcracks) are very frail against tensile …

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 …

The relationships between engineering geology, structural geology, strength properties and
failure mechanisms of several large slope failures in western North America are examined …

ABSTRACT ABSTRACT: In order to tackle the problem of rock slope protection, this paper
presents some results of rock slope simulation of potential toppling failures of varying …

Toppling of individual rock blocks resting on an inclined surface has often been observed in
nature. This instability mechanism has typically been analysed for simple block geometries …
