摘　　要：以平行桁架式人行钢引桥为例,通过采用Civil Midas建模,计算了五种钢引桥主桁架布置形式,分析了钢引桥主桁架构件的受力情况,阐述了不同主桁架布置形式下的主要差异,得出了一些有价值的结论,对于平行弦桁架式人行钢引桥设计具有一定参考意义。Taking parallel truss type pedestrian steel approach bridge as an example,by using Civil Midas modeling,five main truss layout forms of steel approach bridge are calculated,the stress situation of main truss members of steel approach bridge is analyzed,and the main differences under different main truss layout forms are expounded.Some valuable conclusions have been drawn.The conclusions have certain reference significance for the design of parallel string truss pedestrian steel approach bridge.
