Surficial stability evaluation of the slope surface for safety factor against surficial failure shall be based either on analysis procedures for an infinite slope with seepage parallel to the slope surface or on other methods approved by the department.
Several methods are available to assess slope stability and/or review the geotechnical aspects of mine designs prior to implementation.
A slope is an inclined boundary surface between air and the body of an earthwork such as highways, cut or fill, railway cut or fill, earth dams, levees and river training work. The slope stability analysis is crucial in engineering practice to ensure the stability of structures and prevent loss of human life and money.
This engineer manual (em) provides guidance for analyzing the static stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. Methods for analysis of slope stability are described and are illustrated by examples in the appendixes.

Three test zones were established to evaluate various erosion control materials and methods on the slopes that, in some places, were steeper than 1to--1. Phase i, the preparation work done prior to the installation of the various erosion control systems, included removal of large rocks from the slopes and construction of drain.
Aug 23, 2020 prior to receiving the assignment students have developed an understanding of hillslope processes and slope stability through lecture, class.
Civil engineers evaluate slope stability on the following premise: if a slope is stable enough to resist movement, then it is considered stable; whereas if the movement is too strong for a slope, then it is considered unstable.
Factors of safety are generally used in evaluating slope stability. The factor of safety can be defined as the ratio of the total force available to resist sliding to the total force tending to induce sliding. A stable slope is considered to be in a condition where the resisting forces are greater than the disturbing forces.
Figure 1-3: generally the main items required to evaluate the stability of a slope are the following.
Indicators of heightened potential for slope movement can be assessed by evaluating the following conditions within a region: seismic activity, intensity and duration of precipitation, climatic conditions affecting freeze-thaw, wind velocity, fire severity and frequency, annual groundwater level variations, stream and river erosion, and park construction and maintenance activities.
Rock slope stability assessment is basically used for designing and evaluating the slope stability of the rock and mean while this is used for safety of the mine site.
