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 that deformation of the panel can be constrained by adding a vertical auxiliary geobelt at the end of the main geobelt.The research content of this paper can provide reference for the economic rationalization design of the reinforcement form in the actual project.
