A deformation evaluation procedure for reinforced soil walls is proposed based on the findings of parametric studies using SSCOMP. This deformation evaluation procedure may be used as a serviceability design check for reinforced soil walls, constructed with either inextensible or extensible reinforcements, standard or non-standard configurations. The maximum facing deformation for a wall with “standard” configuration is first determined from a design chart produced using a well-validated finite elemeµt program SSCOMP. The deformation of walls with non-standard configurations can then be computed by multiplying the standard wall deformations by appropriate modification factors, termed “deformation indices”. Use of the deformation eval’uation procedure will give estimates of specific deformation values at working stress conditions. The proposed deformation procedur_e was validated by field walls and test walls with different reinforcements and configurations.
