生态框挡土墙在堤防工程中的应用

Application of Ecological Frame Retaining Wall in Embankment Engineering

堤防工程中常见的堤防型式包括均质土堤、土堤结合防浪墙、土堤结合浆砌石挡墙、防洪墙等,在实际应用过程中存在生态效果差、环境适宜性差、征地难度大等问题,难以契合“人与自然和谐共生”的治河理念。生态框挡土墙作为一种较新的型式,目前应用相对较少。以新建堤防工程为例,结合工程建设实际需求,对拟采用的5种堤防型式进行综合比选,并对生态框挡土墙进行设计。应用结果表明:生态框挡土墙在生态河道建设中优点突出,兼具防洪效益、生态效益、环境效益和社会效益。

In embankment projects,common embankment types include homogeneous earth embankment,earth embankment combined with wave wall,earth embankment combined with masonry retaining wall,flood wall,etc.In the practical application process,there are problems such as poor ecological effect,poor environmental suitability,and great difficulty in land acquisition,which are difficult to fit the river management concept of“harmonious coexistence of human and nature”.As a relatively new type,the ecological frame retaining wall is relatively less used at present.Taking the newly built embankment project as an example,combined with the actual needs of the project construction,this paper makes a comprehensive comparison and selection of five types of embankments to be adopted.The results show that the ecological frame retaining wall has prominent advantages in the construction of ecological river courses,and has flood control,ecological,environmental and social benefits.
