利用通用的有限元软件 ,建立南部嘉陵江大桥主跨两孔危桥状态、加固各阶段、加固后运营状态有限元模型 ,计算分析危桥状态和运营状态主拱圈极限承载力以及加固各阶段主拱圈在自重作用下内力变化情况 ,说明加固措施的可行性。
The common finite element software was used to establish the state of dangerous bridge with two holes in the main span of Jialing River Bridge in southern China and to reinforce the operational state finite element model of each stage and reinforced state to calculate and analyze the ultimate bearing capacity of the main arch and the main stage of reinforcement Arch ring under the weight of the internal force changes, indicating the feasibility of reinforcement measures.
