The highway always goes through the goafs.The goafs exert significant impact on the cut slope stability.FLAC3D is based on finite difference method

it has powerful function to simulate the rock and soil behavior.In this paper

take a national traffic program for example

FLAC3D is used to analysis the stress and displacement of the highway cut slope with goafs after grouting and anchoring.The results show that the cut slope is stable after groutal and reinforced and FLAC3D is feasible to evaluate the stability of the highway cut slope with goafs.
