Summary:The layout of reinforcement is an important problem in the design of reinforced earth retaining wall.In this paper,the influence of reinforcement form on the deformation performance of reinforced earth retaining wall is studied through the sand box model experiment on reinforced earth retaining wall with different forms of reinforcement.The analysis of the experimental results shows that,under the condition of equal reinforcement area,the deformation of the mesh stiffened panel is more uniform,and the strip-type cloth-stiffened panel is easy to have large local deformation in the middle and lower parts.For strip reinforcement,shortening the single geobelt’s length,or increasing the density of geobelts with the same length,or the having upper geobelts is longer than the lower ones with the same layout density,can improve the stability of the wall.For grid reinforcement,the stronger the strength of reinforcement node is,the better the wall resistance to deformation.In addition,the experiment also illustrates th
