The invention provides an anti-seismic tunnel structure. The anti-seismic tunnel structure sequentially comprises an outer layer lining (10), an anti-drainage layer (20), a flexible filling layer (30)and an inner layer lining (40) from outside to inside, wherein the outer layer lining (10), the anti-drainage layer (20), the flexible filling layer (30) and the inner layer lining (40) are in a circular ring shape; a plurality of anchor rods (11) are uniformly connected with the outer circumference of the outer layer lining (10), the anti-drainage layer (20) is attached to the inner wall of theouter layer lining (10), the flexible filling layer (30) is composed of a filler, and the deformation performance of the flexible filling layer (30) is larger than that of the inner lining (40); and the filler fills between the inner lining (40) and the anti-drainage layer (20), and has discreteness. By arranging the flexible filling layer between the outer lining and the inner lining, the anti-seismic performance of the i
