摘要
文章首先运用Midas Civil软件对桥梁建立有限元模型,然后对桥梁在恒荷载和温度荷载施工工况下进行数值模拟分析,最后对桥梁施工预拱度进行计算分析。通过对桥梁施工监控计算来保障桥梁施工过程中结构安全、使桥梁成桥线形符合设计方案以及使桥梁成桥后结构内力达到最优状态。
In this paper, the finite element model of the bridge is established by using Midas Civil software, and then the numerical simulation and analysis of the bridge under constant load and temperature load construction conditions are carried out. Finally, the pre-camber of the bridge construction is calculated and analyzed. Through the bridge construction monitoring and calculation the structural safety in the process of bridge construction is ensured, so that the bridge is built into a linear shape in line with the design scheme, and the internal force of the structure after the completion of the bridge can reach the optimal state.
