description The invention relates to the technical field of tunnel protection structures, and provides a gypsum rock resistant tunnel protection structure which is composed of an arched arch wall and a bottom plate formed by pouring reinforced concrete and further comprises a fixing rod, the fixing rod is fixed in the arch wall and the bottom plate, and a protection pipe made of hard materials is fixed to the fixing rod. The protective pipe penetrates through the arch wall and the bottom plate and extends into the rock wall, and a heating pipe is fixed in the protective pipe; the cross section of the bottom plate is triangular along the radial direction of the tunnel, I-shaped reinforcing ribs are fixed in the bottom plate, and the two ends of the bottom plate are respectively and fixedly connected with arch feet of the arch wall. By arranging the fixing rod, the protective pipe, the heating pipe, the triangular bottom plate and the reinforcing ribs, control over water in the rock wall where the gypsum rock is buried is
