The accuracy calculation of the structural load calculation of shallow buried bias tunnel is one of the important factors that affect the tunnel's construction.Based on a real case and combined with the rock load cal-culation theory of shallow bias tunnel,this paper anaygzed the shollow tunnel in different bias angle and the thickness of the over burden soil layer.The vertical surrounding rock pressure,later pressure and its coefficient and the repture angle changes was then calculated.This paper will provide technical support for the coustruction of the tunnel.
