摘要
介绍了朝阳南大桥的病害 ,并用空间有限元进行了分析 ,对大节点进行了局部受力分析 ,分析了刚架拱桥大节点产生裂缝的受力原因 ;另外对微弯板进行了空间受力分析 ,说明了微弯板产生病害的机理。
South Bridge in Chao Yang deseases were introduced in this paper,and were analysed by space finite element method,cracking reasons of large gusset of rigid frame arch bridge were analysed,the desease principle of micro-curved plate was specified.
