摘　　要：北京新工人体育场改造复建项目屋盖为超大悬挑大开口空间单层拱壳钢结构,拱壳中部设置的大截面受压环结构重量重、安装高度高,结构安装及精度控制难度大。根据支撑体系设计、结构荷载加载顺序的不同,进行不同工况的施工仿真模拟计算,经过支撑及结构的应力应变对比选择合适的支撑形式及结构安装顺序。The roof of the renovation and reconstruction project of Beijing New Workers Stadium is a single-layer arch shell steel structure with super large cantilever and large opening space.The large-section pressure ring structure set in the middle of the arch shell is heavy and has a high installation height.Structural installation and precision control are difficult.According to the design of the support system and the loading sequence of the structural load,the construction simulation simulation calculation of different working conditions is carried out,and the appropriate support form and structural installation sequence are selected according to the comparison of the stress and strain of the support and the structure.
