Research on Prefabricated Three-Dimensional Ecological Vegetation Protection Retaining Wall
As the country gradually increases its emphasis on ecosystems,the concept of a three-dimensional ecological protection system for highway slopes has also been proposed.The requirements for subgrade retaining walls are no longer limited to support performance,but also add ecological aesthetics requirements.This paper proposed two three-dimensional ecological vegetation protection systems that combine prefabricated retaining walls and three-dimensional vegetation.The concrete consumption and CO2 emissions of the two retaining walls are compared and analyzed with gravity retaining walls under the same conditions.It is found that compared to gravity retaining walls,the concrete cost savings of the two types of retaining walls are 80.57%and 83.21%.These two types of ecological prefabricated retaining walls not only solve the problem of high energy consumption in traditional cast-in-place retaining walls,but also achieve a perfect combination of structure and environment,with high economic and social benefits.
