Abstract: Based on the elastoplastic theory and FEM, the simulation model for analyzing the stability of bedding rock cutting slopes is established. According to the engineering condition of high bedding rock cutting slopes in Yichang-Enshi Expressway in the Hu-Rong national main trunk, the stability sensibility of the bedding rock cutting slope to the influence factors, such as strength of the structural surface, thickness and inclination of rock stratum, is analyzed. The stability regularities of bedding rock cutting slopes are researched. The results show that the strength parameters of the structural surface play a main control role to the stability of bedding rock cutting slopes; and the rock stratum inclination has obvious influence on the stability of cutting rock slopes. In the engineering geological condition, the stability of the bedding rock cutting slope is in the poorest state when the rock stratum inclination is about 38°.

Key words: bedding rock slope, cutting slope, stability, FEM
