To research the mechanical regularity of steel frame in tunnel, Steel frame and Sprayed concrete Combination Model is applied and the large-section loess tunnel of highway is taken as an example. The hoop stress of flange and the radial stress of web were analyzed, the research results show that:The most areas of hoop stress of flange is in press, the compress value which most areas of flank edge is larger than the outer flank flange in the same area of steel frame. The hoop and radial stress of web is in press. The hoop stress value which most areas of flank edge are larger than the radial stress in the same area of steel frame. |
