The invention discloses a double-truss double-arch bridge. The bridge is mainly composed of a main arch (1), an auxiliary arch (2), triangular nets (3), inclined legs (4), a main beam (5) and an outerwrapped concrete section (6); the auxiliary arch (2) is erected between the main arch (1) and a main beam (5), and arch feet of the auxiliary arch (2) are connected with arch feet of the main arch (1) through inclined legs (4); the triangular nets (3) are distributed between the main beam (5) and the auxiliary arch (2) and between the auxiliary arch (2) and the main arch (1); the auxiliary arch (2) is used as a chord member and can form a double-truss double-arch structure together with the main arch (1) and the main beam (5) at the same time, so that the structure is stressed uniformly, andthe integrity is good; and the outer wrapped concrete section (6) is a rigid arm domain, the rigidity of the outer wrapped concrete section is far larger than that of an arch crown, and deformation, bending moment and arch cal
