VI - SLOPE STABILITY RESULTS <br />The SEO requires minimum factor of safety of 1.25 for static condition analyses and 1.0 for <br />pseudo-static (earthquake loading) condition analyses for Class I (high hazard) embankment <br />dams. This design criteria was used to establish the desired minimum factors of safety for this <br />project and should be considered as highly conservative for evaluating alluvial mining high <br />walls. The calculated factors of safety are within the design criteria specified for this project and <br />can be considered indicators of the high wall performance under the various conditions. The <br />results of the static condition and pseudo-static condition slope stability analyses are presented <br />in Table 2 and Table 3. <br />Table 2 - Static Condition Slope Stability Analysis Results <br /> <br /> <br />Description <br />Calculated Factor <br />Of Safety Required <br />Minimum Factor <br />Of Safety <br />Case A 1.31 1.25 <br />Case B 1.33 1.25 <br />Case C 1.31 1.25 <br />Case D 1.30 1.25 <br />Case E 1.28 1.25 <br />Case F 1.34 1.25 <br />Case G 1.32 1.25 <br />Table 3 - Pseudo-Static Condition Slope Stability Analysis Results <br /> <br /> <br />Description <br />Calculated Factor <br />Of Safety Required <br />Minimum Factor <br />Of Safety <br />Case A 1.14 1.00 <br />Case B 1.16 1.00 <br />Case C 1.16 1.00 <br />Case D 1.15 1.00 <br />Case E 1.13 1.00 <br />Case F 1.18 1.00 <br />Case G 1.16 1.00 <br />West Farm Gravel Pit <br />Slope Stability Analysis <br />Page 4
