Abstract

The invention discloses a quake-proof coverage-type reinforced fill structure, aiming at improving the integral stability of a retaining and supporting structure, effectively controlling the deformation of a panel and enhancing the quake-proof capability of a retaining wall. The quake-proof coverage-type reinforced fill structure comprises a panel (30), fillers filled and pressed at the inner sideof the panel (30) in a layering way and an aggregate inverted filter (20) arranged longitudinally. Main lacing wires (10) are arranged in a horizontal, interlacing and layering way; the panel (30) isformed by a split type building block (31) and an integral building block (32) built vertically at intervals; the split type building block (31) is formed by an outer building block (31a) and an inner building block (31b) spliced in a thickness direction of the panel (30); the main lacing wire (10) is rebated to cover the aggregate inverted filter (20) and the inner building block (31b); a vertical tenon connection structure and / or a vertical splicing structure are arranged between the outer building block (31a) and the integral building block (32); and a vertical splicing structure is arranged between the inner building block (31b) and the integral building block (32).

Description

technical field [0001] The invention relates to a reinforced soil structure in civil engineering, in particular to an anti-seismic wrapped reinforced soil structure which can be used in road (railway, highway) subgrade filling works in high-intensity earthquake areas. Background technique [0002] Reinforced soil structure is a relatively mature retaining engineering technology, which is widely used in geotechnical engineering, construction engineering, traffic engineering and water conservancy engineering due to its characteristics of economy, stability, aspect and strong adaptability. Transportation, water conservancy and other industries have successively issued corresponding design codes, such as "Code for Design of Highway Reinforced Soil" and "Code for Design of Railway Subgrade Support and Retaining Structure". Mature. [0003] The traditional reinforced soil structure is mainly composed of ties, fillers and panels. The ties are arranged horizontally, alternately, an...
