FLAC 3D is a widely applied software in geotechnical engineering�� We mainly introduce the principle of strength reduction theory�� Numerical simulation on the K377 + 230 �� k377 + 520 section of a highway has been made by FLAC 3D sofeware based on strength reduction theory�� To calculate the slope lateral and vertical stress and displacement when the slope gets to the initialization equilibrium condition in dead weight function��then to analyze the result that the slope failure mechanism was retrogressive landslide; after that to calculate the slope stability coefficient as 0. 97 through the strength reduction theory��finally to determine the sliding surface by the shear strain increment chart��
