According to the formula of active earth pressure of the existing embankment retaining wall, the expression of anti-overturning and anti-sliding stability coefficient of the retaining wall under complex wall conditions is deduced. The influence of the wall slope on the stability of retaining wall is studied. The influence of the wall slope, the slope of the back wall, the width of the wall and the slope of the embankment on the stability of the retaining wall are analyzed. The differences of the resultant force of the earth pressure and the stability of the retaining wall when the rupture surface is placed at different positions on the top of the slope are analyzed Through the above parameters, some conclusions have been drawn that guide the design of retaining wall engineering.
