| 摘 要： | 结合康复南路跨线桥工程实例，阐述了利用Ansys建立钢管混凝土拱桥模型的一般方法-即首先建立拱桥的空间杆系单元模型。对复杂截面采用写截面的方法，同时在建横过程中使用数组来增强程序的可读性，并提出了施加预应力和吊杆初张力的方法．理论计算与实测结果对比分析表明，本建模方法正确可靠．

| Abstract: | Combining the project of the overpass bridge of South Kangfu Road, this paper has explained the general method for setting up an arch bridge model by using Ansys. It is to set up the rod unit model of arch bridge at first, to adopt the drawing sectional method to the complicated section then, and at last, to use arrays to strengthen the readability of the program in the course of its modeling. The paper, meanwhile, has pot forward a method to exert prestressing force. |
