Geo-Synthetically Reinforcements
Geo-synthetic soil reinforcement, such as geo-grid and geotextile, is another
technique used to
stabilize
slopes. For high embankment on
soft ground, the application of geo-synthetic i. .e., high
strength geotextile or geogrid is
required at
the base of
the embankment to enhance the stability of
the embankment.
6.7.6
Retaining Walls
The most common use of retaining walls for slope stabilization is when cut or
fill is required and
there is
not sufficient space or right-of-way available for just the slope itself. Gravity and cantilever
retaining walls are most common adopted. Examples of wall used are reinforced concrete wall,
sheet pile wall, gabions wall, crib walls.
