Abstract
This paper introduces the main dimensions and drawings, and discusses the static analytical results of a prestressed concrete bridge with slant-legged rigid frame. The numerical mode of this bridge was built by the specialist FEM software. The results show that the central span of box-beam and the slant-legs forms an arch-like structure which brings these members into compressive-bending states, the side span of box-beam is in bending. For the box-beam, the internal forces mainly come from the dead load, the prestress effects and the vehicle load. The sedimentation of supports and the entire warming or cooling have certain influence on the side span box-beam and the slant-legs. Decreasing the shrinkage and creep of concrete is also important for this bridge.
