Abstract According to the first expressway reinforced gabion retaining structure in China(reinforced earth engineering of Daqing—Guangzhou expressway section of Lanxi interchange AK0+939.38–AK1+079.71，BK0+296.55–366.18 in Hubei Province)，the stability of steep reinforced gabion slope is evaluated by using strength reduction finite element method(FEM) on the platform of the finite element software Phase2 V6.0. Based on the results of limit equilibrium slice method，the effect of selected element on the results of strength reduction method is analyzed. A new method to determine the internal failure surface of reinforced earth structure by using FEM to calculate tension distribution of reinforcements is proposed. The influences of cohesion，internal friction angle，tension，earthquake force，gravity density and vehicle load on factor of safety are discussed. Thus，it can be effectively used to guide the specific engineering designs.

Key words： slop engineering finite elements strength reduction method reinforced gabion retaining wall steep slope stability analysis internal failure surface
