%X The high and steep slope of Rucheng-Chenzhou expressway is located between segment K65+410 and K65+680. Since March 2011, deep displacement had occurred in the slope in need of treatment measures. In this article, a slope model with multiple potential slip surfaces is built on the thorough understanding of the site's geological conditions and the deformation mechanisms. The slope stability under different conditions is calculated with the limit equilibrium method. On this basis, treatment measures are put forward, including cutting slope, surcharge reaction and anchor bolts. The results offer basis for the design of high-steep slope treatment.Within 4 years after the treatment, no large-scale deformation occurred, which indicates that the high-steep slope treatment is successful.
