Gabion retaining wall, soemtimes called gabion wall or retaining wall, is formed with gabion baskets stacking atop one another, and it plays a positive role in earth retaining, mud-rock flow prevention, slope stabilization, landslide treatment, and soil erosion control, etc. The walls are regarded as a flexible and free drainage system, which can effectively resist the disturbing forces. During the building of gabion retaining walls, in order to achieve the effect of stability and an aesthetic appearance, it is suggested that the walls should be inclined from the vertical plane by 6 or 10 degrees. The gabion retaining walls' flexibility degree can be determined by the quality of the filling materials, the type of fill, wire diameter of the mesh, and the mesh type. For example, the more angular the filling materials are, the greater care in filling and the heavier the wire diameter of the mesh. Therefore, the requirements on the quality of installation will be higher, thus leading to a more dimensionally stable structure.
