    NEW TECHNIQUE FOR THE ANTI-SLIDING REINFORCED RETAINING WALL

    • 摘要: 本文针对现有加筋土挡墙技术的不足,研究一种新型整体式加筋土挡墙结构,即土工箱+高强土工格室+土体加固剂的防治手段,其结构形式具有运输方便、施工快捷、耐日晒、雨淋,长期化学稳定的性能,既能克服填土的不均匀沉降,又能提供足够的抗滑能力,满足滑坡灾害快速处置的工程需求。本文详细介绍了其结构形式、材料比选、结构设计及生产工艺,并进行了室内大型物理模拟实验。试验表明,土工箱+高强土工格室的加筋方式大大提高了抗滑挡墙的承载能力,比不加加筋材料时提高约45%,比传统加筋方式提高约25%。同时进行了现场承载力实验,现场试验表明,新型加筋土挡墙技术抗滑能力比传统土工合成挡墙承载力提高了63.4%,在滑坡应急处置中有很大应用前景。

       

      Abstract: The structure of a new type of reinforced retaining wall is studied here. It contains the prefabricated panel, the high strength cell and the soil reinforcement. It has the following features: convenient transportation, convenient construction, resistant to sunlight or rain, and long-term chemical stability. It can overcome the uneven settlement of the soil. And it provides enough anti slide forces. So it can be used for rapid disposal of landslide disaster. The structure, the material selection, the structure design and the production technology are introduced in details in this paper. Large scale physical simulation experiments were carried out. Tests show that the new structure greatly improves the bearing capacity of the retaining wall, which is about 45%higher than that without the reinforced material and 25% higher than that of the traditional reinforcement method. The field carrying capacity test was carried out. The soil reinforcing agent is added in two of the tests. The soil reinforcing agent is composed of cement, calcium chloride, sodium silicate mixture by certain proportion. Field tests show that, compared with the traditional retaining wall bearing capacity improved 63.4%.It has a short construction period, and its environmental protection performance is good. It has the anti-sliding ability of slurry retaining wall of the build by laying bricks or stones, less than the concrete retaining wall by about 30%.Its cost is lower than the concrete retaining wall slightly, far higher than that of slurry retaining wall of build by stones of construction cost. The new technology has great application prospects in the emergency disposal of landslide.
