摘　　要：主要计算桁架段的轴力影响线,比较了理论计算的大量、繁重的工作量与ANSYS简明、快捷的有限元计算,并对ANSYS的计算结果与理论计算结果做对照并分析原因,以推广ANSYS对桁架拱桥内力影响线的计算。The design is axial forces influence line calculation of the trussed arch bridge.There is a brightly contrast comparing a great lot and heavy theoretic calculation with concise and shortcut ANSYS calculation.Contrast to the theoretic calculation results with ANSYS finite element analysis results and analyze the causes,so as to spread the calculation of supporting arch bridge inner force effect line of ANSYS.
