wall should be avoided and may be inserted with few berms. The foundation base
of the walls should be 1/10th of the height +30 cm and the wider base should have a
back slope towards the back

ll. Such type of retaining wall should be a well
accepted management technique along the Hill Cart Road.
Sometimes unnecessary huge overburden is imposed on the unstable slope due
to concentration of materials by constructing huge retaining wall with large boulder
and thus fresh slide occurs. To avoid the unnecessary overburden of the concrete
retaining wall at the places of weak lithology of Lower Paglajhora boulder made
retaining wall (Figs. 8.6 , 8.7 and 8.8 ) with wire net could have been the best
procedure. Such method not only reduce the pressure but also helps for easy coming
