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.%结合工程实例,运用数值模拟软件FLAC3D对垂直应力恒定条件下改变水平应力时倾斜软岩巷道围岩的应力、位移变化规律进行了数值模拟分析,得出了如下结论:随着水平应力的提高,巷道两帮应力集中范围变化不大,顶底板应力集中范围变大,应力峰值向巷道深部转移,其中右肩的剪应力集中程度大于左肩;巷道顶底板垂直位移及两帮水平位移均呈增大趋势;相同水平应力条件下,倾斜款岩巷道变形具有非对称性.
