摘　　要：对采用移动支架安装法的柱面网壳进行施工全过程跟踪分析,结果表明并不是所有杆件的最大内力均出现在施工结束时,没有跟踪施工过程进行分阶段设计计算的常规设计方法,计算结果存在偏不安全的误差,应强调施工内力分阶段设计计算的重要性。Mechanics analysis of a barrel vault grid structures in the course of construction is researched.The calculation results indicated that not all of the largest internal force value exists in the end of construction.Since not considering construction method and construction process,the calculation results of popular design method are not safe.It is very important to design a large span structures by following the construction process.

关 键 词：柱面网壳 施工内力 设计误差
