Based on it, the research content of this dissertation has been determined. Tuan Shan River Bridge is selected as an example and APDL is used to analyze the elastic properties. After calculating the internal force influence surface of assembly skew hollow slab bridge, the internal force-controlling section is attained; the transverse distribution of internal force is studied and the transverse distribution coefficient is parametric analyzed. Based on the results, relation formula of transverse distribution coefficient between skew and perpendicular bridges are fitted. Practical calculation method for the internal force calculation of assembly skew hollow slab bridge is offered. Some conclusions are drawn from comparing and analysing the internal force, bearing reaction and deformation of both assembly and monolithic skew slab bridges.
