Based on the design of rock slope of deep cut in Guanling Xingren Highway of Guizhou Province, the Paper proposes the general principles which should be followed in the design of rock slope of deep cut for high grade highways in mountainous hilly areas.

Observation and analysis of cutting slope settlement in permafrost region;

Simulation analysis of elastoplastic FEM for stability of bedding rock cutting slope;

Analysis of cutting slope reinforcement in swelling rock and soil;
