NEW TECHNIQUE FOR THE ANTI-SLIDING REINFORCED RETAINING WALL

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.
