摘　　要：钢结构支撑体系的卸载是钢结构施工中的重要环节。卸载施工前应进行计算分析、确定卸载方案、确定卸载组织机构,卸载时应重视各项监测数据,做到同步卸载、变形协调、分级循环,将承重支架荷载逐步转换到结构上。通过大量施工实例,总结出机械螺旋千斤顶卸载工艺、砂箱卸载工艺、液压千斤顶卸载工艺、可供同类施工参考。Unloading of steel structure supporting system is an important part during construction of steel structure. Before unloading, calculation and analysis shall be made to determine the unloading scheme and unloading organization; during unloading, various monitoring data shall be observed to realize synchronous unloading, deformation coordination, graded circulation and transfer of load from the weighing support onto the structure gradually. According to abundant construction practices, mechanical screw jack unloading process, foundry flask unloading process and hydraulic jack unloading process are summarized to provide references for similar constructions.
