Abstract
  In rock slopes, block toppling failure is a prevalent instability. In this instability, rock mass consists of a series of dominant parallel discontinuities that are dipping steeply into the slope face, and a series of cross-joints are located normal to the dominant discontinuities. Blocks may slide or ...  Read More

Numerical Modelling of Slide-Head-Toppling Failure using FEM and DEM Methods

H. Sarfaraz; A.R. Bahrami; R. Samani

Volume 13, Issue 1 , January 2022, , Pages 269-280

https://doi.org/10.22044/jme.2022.11698.2159

Abstract
  A common instability in the rock slopes is a toppling failure. If this type of slope failure occurs due to another kind of failure, it is considered as the secondary toppling failure. A type of secondary toppling failure is the slide-head-toppling failure. In this instability, the upper portion of the ...  Read More

Numerical Modeling of Rock Slopes with a Potential of Block-Flexural Toppling Failure

H. Sarfaraz; M. Amini

Volume 11, Issue 1 , January 2020, , Pages 247-259

https://doi.org/10.22044/jme.2019.8887.1778

Abstract
  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 ...  Read More

Numerical analysis of slide-head-toppling failure

Volume 10, Issue 4 , October 2019, , Pages 1001-1011

https://doi.org/10.22044/jme.2019.8521.1731

Abstract
  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 ...  Read More
