The dashed line for the factor of safety
of 1.0 gives the range of shear strength parameters for the slope in the limit equilibrium state.
The proposed failure mechanism is validated using previous studies with respect to the static factor of safety
. The critical yield acceleration coefficient of an earth slope is evaluated by employing the pseudo-static method within the limit analysis framework.
So far, there are three types of safety factors [2, 3,19]: (1) the strength reserve factor of safety
obtained through lowering the strength of rock and soil mass; (2) the overload reserve factor of safety
obtained through increasing the exterior load; (3) the driving force overloading reserve factor, a design value of landslide thrust calculated through amplifying the driving force along the slope while keeping the corresponding resisting force constant.
In the limit equilibrium based infinite slope stability analysis, the slope failure will occur when the factor of safety
is below one (FS < 1), and the critical state is obtained when the factor of safety
is equal to one (FS = 1).
The susceptibility of landslide can be calculated using Factor of safety
(FS) according to Wang, et al., 2007).
If the coupling was perfectly aligned, the factor of safety
is over 5 and the coupling would normally have infinite life.
Outputs include fatigue life, damage, factor of safety
, stress biaxiality, fatigue sensitivity as shown in Figures.
Analysis results can generate contour plots of fatigue life, damage, factor of safety
, and stress biaxiality, as well as rainflow matrix, damage matrix, fatigue sensitivity, and hysteresis.
Water mounding resulting from earthquake-induced warping of covers of waste containment systems may result in time-dependent reduction of post-earthquake factor of safety
against instability (FS).
There's greater reliability and a more uniform factor of safety
," said Firas Ibrahim of FHWA's office of bridge technology.
Results of slope stability analyses are most often given in terms of a factor of safety
, which is the ratio of the driving forces to the resisting forces.
