4. Conclusion An attempt made on clayey backfill soil stability resistance when is subjected to the seismic loading in the three directions simultaneously. The cracked zone of backfill analytically was calculated. The cohesion and the density of the clayey soil become parameters in the analytical process. The NFEM and statistical models are using for simulation of seismic resistance of clayey backfill soil. The displacement mechanism of the model with and without the extending cracked zone evaluated. The results showed the cracked zone is associated with the nonlinear displacement of the backfill model. The elimination of the cracked zone is significantly minimizing the displacement and improving the seismic stability of the model. It understood improving the tensile strength of the soil is required to control load transmission. Future research work is required to consider an economical method for the construction of backfill with the highest level of tensile strength and minimum crack. In addition, controlling and transmission of the seismic loading at the whole model with maximum structural seismic resistance need to investigate.
