Abstract: Based on finite element strength reduction in the slope stability analysis, the foundation of nonreinforced ground, level reinforced foundation and a new reinforcement (horizontalvertical, referred to as H-V) foundation were multiple simulated by ABAQUS software. The effect of H-V reinforced foundation on foundation bearing capacity was analysed by using safety factor Fs. The development of plastic zone and the final destruction of the failure surface in the increasing process of the foundation of strength reduction coefficient can be obtained by using ABAQUS post-processing functions. The results show that foundation bearing capacity can be greatly improved because of reinforcement H-V, ground failure mode would have some degrees of changes because of H-V reinforcement.

Key words: strength reduction finite element method； horizontal-vertical （H-V） reinforced foundation, bearing capacity, reduction factor, depth of reinforcement
