Building a reinforced soil wall with geogrids at hillside
The design parameters for reinforced
padding, retained soil and foundation
floor are shown below:
* Reinforced filling: cohesion 0, friction
angle of 34° and specific weight of 14
KN/m3
* Retained soil: cohesion 5 KN/m2,
friction angle of 28° and specific
gravity of 18.5 KN/m3
* Foundation soil: cohesion 15 KN/m2,
friction angle of 24.6° and specific
gravity of 18.5 KN/m3
* Live load (traffic load): 12 KN/m2
* Dead load (concrete pavement): 3.6
KN/m2
* Minimum FS for static analysis of 1.3
and for the dynamic case of 1.1
The results of the analysis described
above are shown in Figures 4, 5a and 5b.
Now, using the Sierra Bank and varying
the values of friction angle (35.3°)
and specific weight (21 KN/m3), the
following results are obtained as follows
in Figures 6a and 6b.
With these results, it can be inferred
that with a heavier material like concrete
(specific weight = 24 KN/m3), a failure
due to global stability might happen if a
concrete wall is used.
