As mentioned above, we have carried out a parametric analysis to also check the impact of increasing the surcharge load at top of the slope. As shown in the table below, even after increasing the surcharge to 200 kN/m2, the factor achieved will still exceed the factor of safety of 1.4 as per BS 6031.
