Reinforcement Pull-out Resistance

The resistance of reinforcement against pull-out from the earth body is calculated from the input parameters of the geo-reinforcement and the normal force acting in the direction normal to its area:

  • Standard calculation:

where:

Tp

-

bearing capacity against tearing

L

-

reinforcement length (from front face to its end)

Ci

-

coefficient of interaction between soil and geo-reinforcement

σz

-

vertical geostatic stress

φ

-

angle of internal friction of soil

Note: In the "Redi-Rock Wall" program, the pull-out resistance calculation takes into account the scale correction factor α.

  • according to EBGEO (only in the "MSE Wall" program):

where:

Tp

-

bearing capacity against tearing

L

-

reinforcement length (from front face to its end)

λi

-

coefficient of interaction between soil and geo-reinforcement

σz

-

vertical geostatic stress

φ

-

angle of internal friction of soil
