摘　　要：某巨型拱-吊柱结构体系复杂,传力路径长、冗余度较低,为保障结构实施过程安全可控,对其施工过程进行分析和监测,极为必要。采用有限元分析软件对其进行施工全过程数值模拟分析,并基于分析结果提出针对性的监测方案。研究结果表明,施工过程实测应力值和变形值与理论值稍有差别,变化规律基本相符,构件总体应力比较小,材料处于弹性阶段,结构处于安全状态。The structural system of a giant arch suspension column is complex,with a long force transmission path and low redundancy.In order to ensure the safety and controllability of the structural construction process,it is extremely necessary to analyze and monitor its construction process.Use finite element analysis software to conduct numerical simulation analysis of the entire construction process,and propose targeted monitoring plans based on the analysis results.The research results indicate that there are slight differences between the measured stress and deformation values during the construction process and the theoretical values,and the variation pattern is basically consistent.The overall stress of the components is relatively small,the material is in the elastic stage,and the structure is in a safe state.
