The use of the graphical stability analysis has enabled the geotechnical engineers to quickly and accurately evaluate the stability of slopes designed in jointed rock. This method has been utilized as a design tool over the past four years and has proven successful on numerous projects in Pennsylvania in varying rock types. A post construction study was undertaken on all the projects designed by this method. The overall purpose of the investigation was to evaluate the stability of the constructed cut slopes and compare it with that predicted in the original design, thus establishing the credibility of the analysis method. This study has shown that the method is an extremely efficient way to evaluate slope stability in jointed rock. As a result of this investigation a manual was produced based on a modified graphical stability analysis, developed by the Pennsylvania Department of Transportation. This manual is now being used successfully on a statewide basis. /Author/
