Verification – theory of limit states

The analysis checks whether the passive (resisting) forces Fp acting on a slip surface are greater than the active (shear) forces Fa:


where: G - gravity force
Sa,sv - vertical component of active pressure
Sa,vod - horizontal component of active pressure
di - length of  ith section slip surface
d - length of slip surface
Fh,n - bearing capacity of nth nail behind slip surface per 1 running meter
ci - cohesion of  ith soil layer
φi - angle of internal friction of ith layer
υ - inclination of slip surface
α - inclination of nails from horizontal direction
