摘要
结合大跨高墩曲线箱梁连续刚构施工监控项目 ,分析此类桥梁悬臂施工中产生空间变形的主要因素 ,并介绍针对此空间变形应采用的施工控制措施 ,以保证桥梁建成后的线形状态。
By using the spacial analysis software,ANSYS,the mechanic characteristic of variable cross-section PC continuous curved box girder bridge is analyzed and influences of high pier applied on cantilever casting are researched too,then geometric control methods are proposed in cantilever construction.
