Abstract

The invention discloses a flexible reinforced earth structure based on an 8-shaped tyre and relates to a reinforced earth structure. A basic unit structurally comprises 8-shaped waste tyres (10), high-strength plastic bolt nuts (20) and building padding (30). The high-strength plastic bolt nuts (20) are connected among the 8-shaped waste tyres (10), and the building padding (30) is paved at holes inside and outside the 8-shaped waste tyres (10). The 8-shaped waste tyres (10) are arranged in a plane transversely and longitudinally to form a planar net structure. A three-dimensional net structure is composed of a plurality of layers of vertical planar net structures. The flexible reinforced earth structure is easy to compact and avoids damage caused by too much deformation. The reinforced earth structure is good in ductility and durability, low in modulus of deformation, high in damp and good in seismic resistance and has good deformation adaptation and long-term stability. The reinforced earth structure is simple, convenient to construct and low in cost, fully uses waste and earth materials on the field and reduces environment pollution and covering area.

Description

technical field [0001] The invention relates to a reinforced soil structure, in particular to a flexible reinforced soil structure based on a figure-eight tire. Background technique [0002] Most geotechnical projects such as roads, railways, foundations, slopes and embankments use conventional geosynthetic materials such as geotextiles and geogrids to reinforce soil structures. This technology is relatively mature and has been widely used in the world. However, conventional flexible reinforced soil structures are mostly reinforced with geosynthetic materials, and their structure, tensile modulus, ductility, and surface properties are inferior to those of tire-reinforced soil structures. [0003] The data of Taiwan Ji-Ji earthquake, Wenchuan earthquake in my country, Hanshin earthquake in Japan and North Ridge earthquake in the United States show that geosynthetics have certain seismic performance. If the horizontal seismic action and gravity action are synthesized into a q...
