The invention discloses a subway double-line tunnel lining structure manufactured through a cut and cover method. The structure comprises a vault and a vault bottom which are connected in an end-to-end mode. The section of the vault is semi-circular, the section of the vault bottom is of a semi-ellipse shape, and the vault and the vault bottom form a composite lining through primary support and secondary lining. Due to the fact that the structure of the section of a tunnel lining is optimized, structure stress in an operational period is improved, it is guaranteed that the lining structure can bear the action of water and soil loads and other extra loads, the sizes of the sections of the structure can be reduced as much as possible, the number of ribs of the lining structure is reduced, and project cost is lowered.
