Research on Construction Technology of Three-Dimensional Reinforced Rigid-Flexible Composite Ecological Retaining Wall

Abstract

The conventional subgrade slope usually adopts masonry protection. As the wall top is difficult to be provided with water proofing, the construction quality can’t be guaranteed. Thus, during the rainy seasons, rain infiltrates downward along the wall body to make the soil body behind the wall to be soaked to settle, which leads to subsurface erosion and finally damages the facing wall and the slope. The masonry retaining wall needs to consume a large amount of stones, and the wall surface can’t be planted, which doesn’t conform to the national requirements on energy-saving and consumption-reducing and ecological highway development. This paper innovates on the conventional retaining wall technology and introduces a newly-researched construction technology of three-dimensional reinforced rigid-flexible composite ecological retaining wall, which greatly improves the integrity and anti-deformation capability of the soil body behind the wall, reduces the subsidiary stress on the foundation base, improves the bearing capacity of the foundation, and the anti-sliding and anti-overturning stability of the retaining wall.
