Applying the theory of structural topological variation,the peper puts forword a new analytlcal method for the fixed- ended arches with variable cross-section,It offers the expressions of the influence lines of internal forces and the computing expressions of internal forces and displacements.
本文根据论文《弹性结构拓扑变化的一般定理及拓扑变化法》提出的结构拓扑变化的理论，对变截面无铰拱用拓扑变化法进行了结构分析，得出了一套全新的绘制无铰拱内力影响线的方法，并由此导出了其影响线的显示表达式及内力，位移计算式，该方法彻底摆脱了组建及求解代数方程组并实现了结构拓扑变化分析与有限元分析的结
