Abstract: In view of the problem of the stress of the surrounding rock in the tunnel with inclined seam，the numerical model for different inclined angle was established.The stress of surrounding rock under action of ground pressure in the inclined seam was calculated.It was concluded that the concentrate stress was shift to the up corner angle while the angle of seam was between 30° and 40°.And the concentrate stress was shift to the down corner angle while the angle of seam was between 50° and 60°，and it was shift to the up corner of the down part.While the angle of seam was larger than 40°，the asymmetry was clearly and it becomes larger when the angle is larger.The stress of surround rock enlarged linear with the angle.When the angle was between the 10° and 50°，the enlarged factor was between 0.5 and 2.3.When the angle was between 50°and 80°，the factor was about 0.5.To the factor of asymmetry，it was larger when the angle was bigger.When the angle was between 30° and 80°，the factor of asymmetry was about constant and it can be concluded that the stress of surround rock was in the situation of asymmetry under the dynamic pressure.
