Abstract：Based on the in-situ tests and theoretical analysis，a simplified method，which can be used to analyze the stability of soil-nailed wall，is proposed. The simplified method assumes that the fixed circular potential failure surface passes through the toe of the wall and intersect the top at about 0.36 H，and trapeziform earth pressure along the depth of the wall. This method has the advantage of avoiding the tedious processes of trial and error to search the potential failure surface. The calculation results of two engineering projects show that the proposed method has its practical value.
