| 摘 要： | 针对工程工期和气候条件要求的实际情况,将满堂支架法和全挂篮悬臂施工法相结合。文章探讨了混合施工方案对桥梁结构受力状态的影响。采用施工全过程空间数值分析方法,对比研究了全挂篮施工方案和采用混合施工方案所得到的桥梁内力及变形变化特征。研究结果表明,在设计目标确定的前提下,不同的施工方案均能使桥梁成桥阶段内力和线形逼近设计状态。

| Abstract: | According to the requirement of project period and climate conditions,full scaffold method is combined with full hanging basket cantilever construction method.This paper has discussed the influence of mixed construction scheme on the stress state of bridge structure.With whole construction process space numerical analysis method,this article has studied the full hanging basket construction method and the bridge internal force and deformation characteristic got in the mixed construction scheme.The results show that in design goals,different construction schemes can make the internal force and line of bridge in finished bridge stage approximate design state. |
