用奇异函数法分析复杂载荷下实体三铰拱内力

The Use of a Singular Function Method to Analyse the Inter nal Forces of a Solid Three Hinged Arch Subjected to Complex Loading

用奇异函数法导出了实体三铰拱在复杂载荷作用下内力的解析解，与传统的数解法相比，由于用统一的解析式表达内力，便于编程计算。

This paper presents analytical solutions of internal forces of a solid three hinged arch subjected to complex loadings by a singular function method. Compared with the traditional numerical method, the present solutions provide a convenience of programming and designing reasonable arch axes under known loading.
