Supporting structure for highway tunnel body

The utility model discloses a highway tunnel body supporting structure which comprises a tunnel body main body and a primary supporting assembly, and the primary supporting assembly comprises an inner side protective net attached to the inner wall of the tunnel body main body, a reinforced concrete layer poured on the inner side protective net and an outer side protective net arranged on the outer wall of the reinforced concrete layer. The adhesion force of the reinforced concrete layer and the inner wall of the tunnel hole body is increased through the inner side protective net, the outer side protective net limits the outer layer of the reinforced concrete layer, and the situation that a structure on the reinforced concrete layer falls off to crush passing vehicles is prevented; the rubber energy dissipation springs are arranged between the steel arch frames and the protection edges, and vibration energy generated by passing vehicles on the pavement structure layer is dissipated through the rubber energy di
