Abstract:
The lack of friction between soilbags was the main reason for poor integrity of soilbag flexible retaining wall. At present,there are few researches about how to enhance integrity of soilbag retaining wall. In order to improve the wall structure of the traditional soilbag retaining wall,integrated soilbag flexible retaining wall structure which has the advantages of good integrity,and strong ability of deformation coordination was proposed. Combined with the laboratory model test,the wall displacement and stress distribution law of the tension device were studied under the vertical and horizontal loads of integrated soilbag flexible retaining wall structure with sand as filler. A comparison is made between the flexible retaining wall and the traditional soilbag and the reinforced retaining wall in terms of the horizontal bearing capacity,deformation mechanism and stability. The flexible retaining wall produces an integrated effect and formes a continuous wall,which effectively controls the deformation of the wall surface and improves the deformation ability of the wall,so the stability and horizontal bearing capacity are higher than that of the conventional soilbag retaining wall.
