slopes that are prone to failure and collapse by sliding can be enhanced and
made serviceable, safe and secure. For this numerous efficient and reliant
methods are used to stabilize the slopes. The methods usually engage one or more
of the following measures, which either reduce the mass that are vulnerable to
cause the sliding and collapse or successfully helps improving the shear
strength of the soil in the failure zone. 1. Slope flattening reduces the weight
of the mass tending to slide/collapse. It can be employed wherever possible.
2. Proving a berm beneath the toe of
the slope enhances the resistance to movement. It is especially useful when
there is a possibility of a base line.
3. Drainage helps in reducing the
seepage forces and thus enhances the stability of slopes. The zone of
subsurface water is lowered and infiltration of the surface water is
4. Densification by the using
explosives, vibroflotation or terra probe aids in increasing the shear
strength of cohesionless soils and hence increases stability.
5. Consolidation by surcharging,
electro-osmosis or various other reliable effective methods help in
enhancing the stability of slopes in cohesive soils.
6. Grouting and injection of cement
concrete mixture along with other compounds into specific zones help in
increasing the stability of slopes.
7. Sheet piles and retaining wall
structures can be installed to provide lateral support and to increase the
8. Stabilization of the soil helps in
enhancing the stability of slopes.
9. Other relative inexpensive methods
like for slope flattening and drainage control may be usually applied.
