A shock-absorbing panel-assembled reinforced soil retaining wall and its construction method

Abstract

The invention discloses a shock absorption panel fabricated reinforced earth retaining wall and a construction method thereof. The shock absorption panel fabricated reinforced earth retaining wall comprises a retaining wall body and a filling body behind the wall; the retaining wall body is arranged at the front end of a side slope, and the filling body behind the wall is arranged between the retaining wall body and the side slope; and the retaining wall body comprises a fabricated foundation layer, a bottom panel layer, a hard supporting layer, a lower transition panel layer, a shock absorption energy dissipation layer, an upper transition panel layer and a cover top panel layer which are sequentially arranged from bottom to top. The filling body behind the wall includes an inverted filter layer, a geosynthetic material, a geosynthetic filling material in a reinforcement area and filling earth in a non-reinforcement area. The shock absorption panel fabricated reinforced earth retaining wall is formed by assembling a plurality of panels and fabricated foundations, and is connected and fixed by adopting reserved grooves and bulges and a non-horizontal structure, shock absorption energy dissipation panels are applied, on the one hand, damages such as panel falling off and rib material pulling out of the reinforced earth retaining wall under an earthquake condition can be avoided,and the stability and safety of the reinforced earth retaining wall under the earthquake condition are improved; and on the other hand, the operation process in construction is greatly simplified, the construction period is effectively shortened, and the economic benefits are remarkably improved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a shock-absorbing panel-assembled reinforced soil retaining wall and a construction method thereof. Background technique [0002] In the past ten years, my country's economy has developed rapidly, infrastructure construction is in full swing, highway mileage is increasing, and the transportation network is gradually improving. More and more projects are developing in areas with harsher geological conditions, especially after the Wenchuan earthquake in 2008. The emphasis on earthquake resistance is constantly increasing. Compared with traditional gravity retaining walls, reinforced soil retaining walls have obvious advantages in engineering cost, terrain adaptability and earthquake resistance. The wall has good anti-seismic characteristics, but serious damage still occurs under the action of strong earthquakes. The most important damage occurs at the top of the reinforced earth re...

AI Technical Summary

Problems solved by technology

In traditional reinforced earth retaining wall design, in order to reduce the damage caused by earthquakes, measures to increase the rigidity of the panel are often adopted, but the actual effect is not ideal and will increase the cost of the project
