装配式立体生态植被防护挡墙研究

Research on Prefabricated Three-Dimensional Ecological Vegetation Protection Retaining Wall

国家逐渐提高对生态系统的重视,公路边坡立体生态防护体系的概念也随之被提出来,其中对路基挡土墙的要求不再局限于支护性能,还新增了生态美观需求。本文提出了两种装配式挡土墙和立体植被相结合的立体生态植被防护体系,并将两种挡土墙的混凝土用量和CO_(2)排放与同等条件下的重力式挡土墙进行对比分析,发现相对于重力式挡土墙,两种挡土墙的混凝土成本节约量为80.57%和83.21%。这两种生态装配式挡土墙不仅解决了传统现浇挡土墙能源消耗大的问题,还实现了结构与环境的完美结合,具有较高的经济和社会效益。

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 CO_(2) 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.
