A minimum factor of safety of 1.5 is <br /> required for analysis of a slope adjacent to a critical structure (MLRB Section 30, 2018). The <br /> results are presented in terms of factor of safety for the slip surfaces evaluated during the <br /> analysis as shown in Table 2. Based on the results of the analysis and respective factor of safety <br /> values,the slopes presented in cross sections D-1 and D-4 have an unacceptable factor of safety. <br /> Cross sections D-2 and D-3 indicate a stable slope condition with the selected analysis <br /> parameters. <br /> Table 2 Slope Stability Analysis Results <br /> BRIERLEY <br /> ASSOCIATES <br /> Creating Space Underground <br />
