Abstract: Based on an actual project, the paper used numeral simulation software FLAC3D to analyze change rule of stress and displacement of inclined soft rock roadway under different horizontal stresses in condition of invariable vertical stress. It obtained conclusion as follows: the concentration range of stress of the roadway's sides had little change while the one of the roof and floor changed a lot, the peak stress moved to depth of the surrounding rock and the concentration level of shear stress of left shoulder was larger than the one of right shoulder with increasing of horizontal stress; the vertical displacement of roof and floor and horizontal displacement of sides of the roadway increased gradually; deformation of the soft rock roadway was asymmetric under the same horizontal stress.
