STUDY ON THE HORIZONTAL DEFORMATION OF REINFORCED RETAINING WALLS OF SOILS

A new method of calculating the horizontal deformation of the reinforced retaining walls is proposed. Assuming that the reinforced soil retaining wall acts as a coherent block,just like the situation of a conventional retaining wall under the horizontal earth pressure backfill material. The reinforced soil retaining wall is taken as an equivalent anisotropic elastic medium and all the elastic properties are derived. During calculating the horizontal deformation of the reinforced soil retaining wall,the reinforced soil block as a cantilever beam is assumed. The horizontal deformation of the cantilever beam is calculated for pure bend and pure shear modes. The design method is proved to be correct,as compared with testing data.
