Analysis according to the theory of limit states / factor of safety

The verification analysis can be carried out according to the theory of limit states:

where: Movr - overturning moment
γs - coefficient of overall stability of structure
Mres - resisting moment

Soil parameteres (angle of internal friction, cohesion) are in this case reduced using the design coefficients introduced in the frame "Settings". The value of utilization Vu is calculated and then compared with the value of 100%. The value of utilization is given  by:

where: FS - factor of slope stability computed with reduced soil parameters
γs - coefficient of overall stability of structure

The second option offers the verification analysis using the factor of safety:

where: Movr - overturning moment
Mres - resisting moment
FS - factor of safety for overturning
