摘 要：
运用大型有限元分析软件ANSYS,在弹性材料和几何大变形条件下建立实体三维模型,计算、分析弹性无孔洞拱在不同约束、不同荷载、不同截面宽厚比、不同截面高厚比下极限承载力的变化规律,在此基础上提出一些对该类结构设计有益的建议。

摘 要：
By using large scaled finite element analysis softeware,the entity three demensional model was constructed under the condition that the elastic materials were greatly deformed .The dynamic changes of limite-bearing capacity under various restriction,load-bearing,ratio of broad over thickness and ratio of heght over transecfion in transection were calculated and analysized.Some useful suggestion were put forwards.
