The embodiment of the utility model provides a tunnel heat preservation and shock absorption structure. The tunnel heat preservation and shock absorption structure comprises a primary supporting layer, a shock absorption layer, a waterproof layer, a heat preservation layer and a secondary lining layer which are sequentially arranged from outside to inside. Annular damping seams are formed in the primary supporting layer and the damping layer at equal intervals in the extending direction of the tunnel, and the annular damping seams of the primary supporting layer and the damping layer are arranged in a staggered mode. An arc-shaped damping belt is arranged between the damping layer and the waterproof layer and located on the top of the tunnel. The heat preservation layer is provided with a hot water circulation system, and the hot water circulation system comprises a plurality of heat supply water pipes, a plurality of water return pipes and a ground source heat pump device which are arranged in the extending
