Gabion mesh is widely used , which can withstand the different pressure , can be installed and reversed according to surface location. At the same time they must have sufficient capacity to withstand stone weight and other gabions weight placed on the top. They also withstand rain erosion, remains to keep structural integrity. As a new retaining structure, gabion retaining wall has been used more and more, due to its characteristics of low cost, eco-good, a wide range , flexible deformation etc.

Gabion retaining wall:

It is a new type of soft retaining wall structure. Fill the stone of coincident size requirement into flexible iron wire cage to achieve certain porosity, layer-by-layer masonry . Gabion protection applies to along river levee slope or bank protection which invaded by water erosion and storms, and difficult to handle the protection works. It has been widely used in road projects in foreign countries. For example, California's road No.1 Montreal retaining walls, Italian Arezzo Province road SS556, Canadian Ontario to support the road lateral slope of the retaining wall, as well as France, Germany, Norway, Switzerland, UK use the structure for channel slope protection, retaining soil, abutment construction and so on. 
In recent years, this new structure has also been applied in China. For example, as slope protection successfully used in Changjiang River main dike,The Lijiang River slope protection from Guilin to Yangshuo, Fengjie pagoda Landslide Treatment works related to river sections are also adopted some form of gabion retaining wall,and made good use of effects.      

 

Gabion retaining wall advantages
Environmental protection is one of China's basic national policy, construction of retaining wall also need try to make it harmonize with the natural environment, to improve the environmental quality of the road. Because Gabion retaining wall has greater porosity (20% ~ 30%), so no need to set scuppers, dilatation joint and settlement joint can also be a simple layout. Compared with other forms of retaining walls, gabion retaining wall with characteristics of good ecology and low cost, can withstand large deformation without damage.

Compared with other form of retaining wall, gabion retaining wall has the above advantages, but the construction site should be selected in the stone-rich areas, and the stone size, strength, weathering degree should meet the requirements. If long-distance transport of the stone, it will increase the cost, under technical feasibility conditions, should have economical comparison with other forms of retaining walls.
