钢管混凝土系杆拱桥关键节点受力分析

摘要

以具体工程为例，通过建立有限元模型，对钢管混凝土系杆拱桥关键节点的受力进行了分析，并对荷载工况进行了应力分析，以提高桥梁工况的安全系数，从而确保桥梁工程的质量。%Taking specific project as an example,through the establishment of finite element model analyzed the key nodes of steel pipe concrete tied arch bridge,and made force analysis on load construction condition,in order to improve the safety coefficient of bridge construction condi-tion,so as to ensure the bridge engineering quality.
