摘　　要：北京新机场航站楼屋盖采用不规则自由曲面空间网架结构,最大跨度达125 m。对屋盖结构卸载过程进行的数值仿真分析表明,变形及应力监测结果与有限元分析结果吻合度相对较高,卸载计算模型合理正确,卸载过程中整个结构受力稳定,验证了现场施工方案和卸载技术的可行性。The roof of the Beijing New Airport Terminal Building adopts an irregular free- form space truss structure with a maximum span of 107m. The numerical simulation analysis of the roof structure unloading process shows that the deformation and stress monitoring results are in good agreement with the finite element analysis results. The unloading calculation model is reasonable and correct, and the whole structure is stable during the unloading process, which verifies the site construction plan and The feasibility of unloading technology.
