摘　　要：介绍了三种常见钢拱架的构造特点,并利用M IDAS软件建立相应钢拱架的空间有限元模型,得到可微调式钢拱架是较为优化的拱架结构型式。This paper introduces the characteristics of structure and mechanics of the different steel arch centerings,and then builds space finite element model of the different types of steel arch centerings by the use of software MIDAS,finally,the result is obtained as follow： steel arch centering of fine-adjustment type is the relatively optimal construction type of steel arch centering.

关 键 词：钢拱支架 拱桥施工 应力 挠度
