<br />RESULTS OF ANALYSIS - CONCLUSIONS AND RECOMMENDATIONS: <br />Results of all analyses performed will be found in a Table <br />' of Stability Rnalysis Results in the Appendix of this report. The <br />location and orientation of critical failure circles and critical <br />' shear surfaces for proposed conditions will be found on the cross- <br />sections in the map pocket in the Appendix of this report. In most <br />cases, the potential for both circular failures and wedge .and/or <br />plane failures was analyzed. Specified shear surfaces for analyzing <br />wedge or plane failures were arbitrarily selected and typically <br />involve two different configurations for each section analyzed. <br />' As may be seen from the stability analysis results, a minimum <br />factor of safety for the project as a whole and for the presently <br />' proposed slope configuration was found to be 2.402. This factor of <br />safety was associated with a circular mode of failure. Also, as a <br />part of this investigation, the effect on the overall stability of <br />' increasing the exposed slope gradient to something on the order of <br />3:1 was evaluated. It was found that this could be accomplished <br />' while maintaining acceptable factors of safety and that the minimum <br />factor of safety associated with a 3:1 slope would be on the order <br />of 2.139. Again, this factor of safety is associated with a circular <br />' mode of failure. We have been given to understand that for reasons <br />independent of slope stability, a gradient in excess of 3:1 for the <br />refuse disposal area would be considered undesirable. <br />All of the general information described above for each cross- <br />, section analyzed has been summarized on a "Slope Stability Summary <br />Sheet" which will be found in the Appendix of this report. <br /> <br />i <br />J <br /> <br />9 <br />r <br />
