This cracked zone depends on the mechanical properties of soil and types of linear and nonlinear applied loads. The cracked zone nonlinearity is extending with unallowable applying loads and impact retaining wall seismic stability. The nonlinear seismic load significantly influences the load capacity and displacement of the backfill and retraining wall. In the present study, firstly the crack zone developing at the backfill zone predicted by analytical method, and I assume that the nonlinear load developing three deep cracks on the crack zone. The nonlinear finite element method (NFEM) was applying for realizing displacement of the backfill. The crack on the clayey soil become parameters for simulation and analyzing model displacement. The statistical model has verified the accuracy of this investigation. The results revealed the cracked zone is associated with the nonlinear displacement of the backfill model. The novelty of this study relates to introducing methodology for classify influence of backfill crack on displacement and vibration mechanism of the model in all stages of the numerical simulation. The outcome of this analytical and numerical study are illustrating that improve mechanical properties of the soil in cracking zone simulation, significantly is enhanced the economical construction of the backfill and minimizing the displacement of the model. The stability of the earth retaining structure depend on backfill stability which controlling load transmission. © 2021 The Authors. Published by ELSEVIER B.V.
