Application of Geogrid Material in Slope Reinforcements

Retaining walls constructed with geogrid are a new and flexible retaining structure system.They result in fast construction,a cost effective solution,and strong adaptability to different foundation types.Aspects of design and construction of this wall type are briefly introduced in this paper and selected case histories are provided.Compared with the conventional retaining wall types,the geogrid reinforced retaining walls can reduce the cost of the initial investment by one quarter.
