9.4 STABILIZATION THROUGH SUPPORT
The main types of reinforcing materials that have been used for stabilization of slope and embankments include steel reinforcement, piles, retaining walls, geo-synthetics, shotcrete, high strength steel tendons. A number of factors are required to be considered for selection of proper reinforcement material for its long-term capacity such as tensile strength, creep characteristics, installation damage, durability, resistance against pullout and reinforcement stiffness and tolerable strain within the slope.
A number of methods can be used to stabilized slope, each of them can be appropriate for a particular set of conditions. In choosing most appropriate method among the technically feasible options a number of parameters like the purpose of stabilization, availability of time, accessibility of site and cost of repair are required to be considered.
