The scope of this paper is related to study of the gabion wall as retaining structure as well as
load bearing member in hilly areas by considering various engineering factors such as structural
stability, flexibility, aesthetics exposure and economic serviceability by following the design
parameters such as overturning moment, sliding resistant and bearing pressure. Nowadays new
construction methodologies as well design by various software’s come into existent to make it
easy the implementation of structure practically but due to adverse effects of climate changes,
the concept of gabion wall retaining structure plays vital role for road construction in hilly areas
as well as in flooding areas on the river banks. Its common in the recent days that structural
member perform multiple duties for given project, but the concept of gabion retaining wall
perform such type of needs. Gabion wall also control the erosion and scouring of land in flood
protection embankment in the form of retaining structure, e.g. Gi wire retaining wall with
various steps along with apron which provides launching and siltation after a period of time or
high flooding. Such type of gabion retaining wall is used in KP province of Pakistan after high
flood disaster occurred in 2010 on River Kabul District Nowshera.
