The utility model relates to a frost heave resistant structure of a subgrade surrounding a transverse building in a severe cold area. Due to the wind tunnel effect of the transverse building in the cold area, the frosting manner of the surrounding subgrade can be changed and more serious frost swelling or thaw collapse damage can be caused. The frost heave resistant structure is characterized in that insulation boards are attached to the sidewalls and the top wall of the transverse building, each insulation board is covered with a thermal insulating anti-freezing structure layer, and the anti-freezing structure layer is covered with a subgrade filler and extends to the top surface of the subgrade filler; the longitudinal profile of the thermal insulating anti-freezing structure layer is shaped like an inverted trapezoid, the bottom width of the trapezoid is twice larger than the local maximum depth of freezing, the slope of the bevel edge of the trapezoid is not less than 2, the longitudinal length of the thermal insulating anti-freezing structure layer is not less than 20m, and the total thickness of the thermal insulating anti-freezing structure layer is not less than 0.4m; the thermal insulating anti-freezing structure layer is a filler layer formed by blending gravel with element, and the mass ratio of the cement blended is 3-5%. The frost heave resistant structure is used for eliminating the influence of temperatures and frost susceptibility on frostbite swelling of the subgrade and capable of effectively preventing the frostbite swelling problem of the subgrade in a position where frost heave resistant swelling damage happens frequently around the transverse building in the severe cold area.
