The invention discloses a tunnel combined supporting structure suitable for an aeolian sand stratum. By means of the structure, the engineering characteristics of aeolian sand can be sufficiently used, and a pile foundation is arranged as the foundation; when underground water rises, the pile foundation serves as an anti-pull pile, a combined lining structure of a tunnel serves as a beam placed onthe pile foundation, the tunnel is similar to a continuous box girder longitudinally, and the differential settlement is reduced; meanwhile, an advance horizontal rotary jet grouting pile serves as one part of the lining structure, and the supporting capacity is considered; a combined lining is formed through a powerful pre-supporting structure (advance horizontal rotary jet grouting pile), a primary support and a secondary lining, the construction and operation safety is ensured, the primary support and the secondary lining can be properly thinned, and the engineering construction cost is reduced.
