Abstract Research purposes: The Jinan Yellow River Highway and Railway Combined Bridge of Shijiazhuang—Jinan Passenger Dedicated Line is the suspension reinforced continuous steel truss bridge which is the first time used for the railway bridge in China．So for it，the study is done on the number of main truss and the deck style of the highway bridge for laying a good foundation for the next works and providing the reference to the similar works in future．
Research conclusions: ：(1)Compared with the three main trussess，the maximum axial force of truss web increases 24．1％．when the two main trusses are adopted and the bending moment outside the vertical post increases much because of the framing effects．(2)Compared with the two trusses bridge，the reflection span ratio and rotation angle at the end of beam decrease 14％and 12％separately because of the deck load transferring directly and much more structural rigidity being provided by three trusses bridge．(3)The structure weight of orthotropic steel deck plate is 35％ lighter than the steel—concrete composite structure，SO the mechanical behavior of main trusses is improved significantly．Compared with the latter，the maximum axial force of the top chord and the truss web of the former decreases about 34．6％ and 10％ separately．
