摘要
宜昌市夷陵区鄢家河大桥主跨拱圈采用军用梁和钢管组合支架,通过对拱圈混凝土分环分段施工各工况的内力分析,得出了军用梁各杆件内存在严重的强度和刚度不足的问题,并提出了处治措施。
Through calculating and analyzing the endogenic force in the arch ring in different conditions,this paper found out that there existed insufficient strength and inadequate stiffness in the members of the combined-bracket of military truss and steel-pipe and put forward treatment measures.
