摘要
针对现场实际情况本文提出了大跨径钢管拱分两段浮吊吊装的方法、拱肋合龙方案和有限元模型简化方法,通过计算分析确定了合龙过程中的相关技术参数和拱肋力学状态。
To counter the site situation a two segments lifting scheme by floating crane and a closure scheme of the arch rib and a simplified method for the finite element model are put forward in the paper. The relative technique parameters and the arch rib mechanics state during the closure are determined through calculation analysis.
