Table 5: Calculation results

AB1 = Minimum safety factor of Bishop and Morgenstern slope stability analysis method
AB = Minimum safety factor of Swedish arc method
AB4 = Minimum safety factor of Circular slip method
AB3 = Minimum safety factor of Roer method
According to the above results, the slope stability is deemed to be safe.
