柔性挡墙是由土工格室、填土和面板3部分组成,按一定坡度层层叠加形成的一种新型支挡构造物。与常见的支挡构造物相比,除具有结构轻、施工简便、造价低的优点外,还具有能与墙后土体协调变形且保持结构稳定,墙面可绿化、能迅速恢复公路沿线景观效果的特性。为了深入研究其工程应用特性和技术标准。本文依托西汉高速公路项目,通过实体工程施工和现场监测、分析,给出了新型柔性挡墙的施工工艺、施工质量控制标准和检验方法、总体质量评定标准。为这种新型支挡构造物的推广应用提供参考。
Flexible retaining wall is composed of geocell, fill and panel composed of three parts, according to a certain gradient layer by layer to form a new type of support structures. Compared with the common support structure, in addition to the advantages of light structure, simple construction and low cost, it also has the ability to coordinate deformation with the soil behind the wall and keep the structure stable, the wall can be green, can quickly restore the landscape along the highway Effect of the characteristics. In order to further study its engineering application features and technical standards. Based on the project of Xi-Han expressway, this article gives the construction technology, construction quality control standard and test method of the new type flexible retaining wall and the overall quality assessment standards through physical engineering construction and on-site monitoring and analysis. Provide a reference for the popularization and application of this new type of support structure.
