摘要
结合工程实例广西崇左至靖西高速公路古龙山大桥,采用空间有限元软件MIDAS/CIVIL,对高墩大跨小半径曲线连续刚构桥结构悬臂施工阶段和成桥阶段箱梁的空间位移与应力进行计算分析,为箱梁悬臂施工时的线形、应力控制提供理论依据。
Combined with an actual project Guangxi Chongzuo to Jingxi highway-GuLongShan bridge, using spatial finite element software MIDAS/CIVIL to calculation and analysis the structure in construction of cantilever and completion stage beam＇ s displacement and stress. The study may provide some references for linear and stress control during cantilever construction of box girder.
