The invention discloses a T-shaped rigid framework and multi-arch combined bridge structure. The T-shaped rigid framework and multi-arch combined bridge structure comprises multiple substrates positioned below the structure; an arch ring of which two ends are respectively fixed on two adjacent substrates is positioned above every two adjacent substrates; a T-shaped steel member is connected aboveeach substrate; every two adjacent T-shaped steel members are fixedly connected; and a spandrel column for supporting the T-shaped steel member above is arranged above each arch ring. The structure isattractive in appearance, empty in interior and solid in exterior, combined by hardness and softness, combined by virtuality and reality, and rational in stress; most of second-stage dead load and moving load of the structure is transmitted to the substrates through a T-shaped rigid framework, so that 85% or above of horizontal thrust of the substrate designed by a conventional method is eliminated, a technical problem that medium and small span multi-arch arch bridges are constructed in general geological conditions can be solved, and technological innovation that the multi-arch arch bridgeswith the horizontal thrust are constructed in unfavorable geological conditions is realized; and the structure is simple and convenient in construction, does not need special treatment to a foundation, and is low in construction cost.
