Abstract: The stability of high rock slope is analyzed with finite difference method. Comparing the difference between original and excavated slope some conclusions are acquired. The destroy mode is round and cut slippage. The slide face is an arc.So arc method is used to calculate the slope stability. The level and vertical displacement is relatively big. The delamination is evident. The maximum and minor principal stress is vertical. And their direction is inclined at the corner of the slope. The minor principal stress of the excavated slope is concentrated. The maximum one is not evident. Some rock area of at the tip and surface of the slope is tension- stress. And some rock slides towards the empty face.

Key words: fast Lagrangian analysis for continuum, rock high slope, stability analysis
