In slopes with coarse-grained soil or rocks, falls typically occur as the rapid descent of rocks and other loose slope material. A slope topples when a large column of soil tilts over its vertical axis at failure. Typical slope stability analysis considers sliding failures, categorized mainly as rotational slides or translational slides.

During the past few decades, the stability of high rock slopes has become an increasingly important focus of geoscientists and engineers in natural slopes, engineered rock cuts and in large open pits. The excavation of steeper and deeper large open pit mines allows reduction in the waste rock (stripping ratio) and maximises.
Engineering projects often require the excavation of rock cuts that must be safe from rock falls and large-scale slope instability, during both construction and operation.

Rock slope engineering was published in three editions (1974, 1977 and 1981) by the institute of mining and metallurgy in london. The original research for the book at the university of london was sponsored by the mining industry in response to a need to develop design methods for increasingly deep open pits.
Particularly relevant to the present purpose: the design of slopes and foundations as engineering structures. 21 mapping of structural features a description of the rock structure (geometry and nature of discontinuities such as faults and joints) is an essential ingredient in any analysis of rock slope stability or of foundation behaviour.
The design of rock slopes is discussed in this paper much as if an actual cut slope in rock were being designed. First, the en gineering requirements of the cut; second, the geologic condi.
1 effects of water on slope stability very soft, saturated foundation soils or ground water generally play a prominent role in geotechnical failures in general. They are certainly major factors in cut slope stability and in the stability of fill slopes involving both “internal” and “external” slope failures.
In a probabilistic slope stability analysis the input parameters are considered as random variables.
In a moderately jointed rock mass, slope failure is generally dictated directly by the presence of discontinuities, which act as planes of weakness.

Such slopes are susceptible to rapid weathering because, within several months to several years, that is, within the engineering period of time, the rock deterioration process starts both on the slope surface and within the inside of the rock mass. The weathering of soft rocks has been studied with the intention to clarify the process.
