摘　　要：大跨度网架工程分段吊装施工技术的关键在于对网架的合理划分,网架的划分除了要考虑网架自身的结构特点外,还必须充分考虑起重机的起重能力、绑扎点的位置、网架分段间的相互影响,临时支架的搭设,网架分段的刚度和稳定以及吊装工艺的可行性等。The key point of hoisting construction of divided large-spanned grid works lies in the rational division of the grid, in which not only should the structural characteristics of the grid itself be taken into account, but also crane capacity, binding location, interaction of grid sections, erection of temporary supports, rigidity and stability of the grid sections as well as feasibility of hoisting technique should be fully considered.
