Step 4: Utilizing the Figure 1, Circular Failure Chart, with the <br />i calculated dimensionless ratio of 0.41 and 0.47 and a slope <br />angles of 34°, the following Tan 0 is determined: <br />F <br />Tan ~ = 0.21 Minimum <br />F <br />= 0.19 Maximum <br />Conclusion: The factor of safety of the fill slope is estimated to <br />be 1.37 and 2.23 respectively, which indicates long-term <br />stability <br />F = Tan 0 1.37 Minimum <br />0.21 <br />F = Tan ~ = 2 23 Maximum <br />• 0.19 <br />C~ <br />
