摘　　要：广州歌剧院钢结构工程为空间组合折板式三向斜交网格结构。结构面主梁交接处采用铸钢节点,安装过程中需搭设临时支撑胎架。通过ANSYS进行卸载工况分析,实施过程中严格布设传感器,进行同步监测,保证结构安全。结果表明,为减少施工过程对网格整体结构变形的影响,待整体安装完毕后,对支撑胎架进行卸除。卸除方法采用分区同步分级卸载的方法。Space-plate combination of three-fold bias grids is adopted in Guangzhou Opera House.The cast steel joints are selected in structural surface junction with the main beam.Thus,temporary supporting jigs are built during the process of installation.Unloading is analyzed by the means of ANSYS software.The sensors are strictly laid to monitor the structure,which can ensure the safety.The results show that supporting jigs are unloaded after the whole installation as to decrease effects on the whole deformation during the process of construction,by selecting the unloading method of synchronous division classification.
