摘要
哑铃型钢管混凝土拱桥具有良好的整体稳定性和变形刚度,但由于哑铃型截面的特殊结构,缀板处的受力较为复杂。文章以哑铃型钢管混凝土拱桥为工程背景,采用MIDAS/Civil有限元模型对其缀板内注混凝土和缀板内不浇注混凝土的2种浇注方式进行对比分析,结果表明,缀板内不浇注混凝土的方式满足施工、成桥的安全要求。
Dumbbell concrete-filled steel tube arch bridge has good overall stability and deformation,but beacause of special structure of dumbbell section,the stress of batten plate is complex. Taking a dumbbell concrete-filled steel tube arch bridge as an engineering background,two kinds of casting way are analyzed using MIDAS/Civil finite element model. The reasearch results show that batten plate without concrete meets the requirments of construction and bridge.
