earth columns, grounded anchors, networks of micro-piles, soil nailing,
geo-grids for reinforced ground and cellular faces. 6
a. Ground Anchoring. Stabilizing an unstable slope also can be achieved
by the application of active forces to the unstable ground. These forces
increase the normal stress and, therefore, resistance to friction along the
creeping surface. Anchors can be applied for this purpose, linked at the
surface to each other by a beam frame, which is generally made of
reinforced concrete.

b. Micro-piling. installation of a series of micro-piles that make up a
three-dimensional grid, variably tilted and linked at the head by a rigid
reinforced concrete mortise. This structure constitutes reinforcement for
the ground, inducing an intrinsic improvement of the ground characteristics
incorporated in the micro-piles. This type of measure is used in cases of
smaller landslides.
