大跨连续梁桥悬臂施工过程控制机理研究

摘要

结合吴忠黄河公路特大桥施工过程监控，对大跨连续梁桥悬臂浇筑施工过程的几何线形控制进行了分析，得到了最终理论曲线，并和现场实际测得的线形进行了对比，表明了理论及程序计算的可靠性，为该大桥的线性控制提供了依据。%As an engineering example,the theoretical curves of the Wuzhong Yellow River Highway Bridge was analyzed and obtained in detail while the process of cantilever casting construction was considered. Compared with the actual curves,the results demonstrate the theoretical sim-ulation and related program are reliable. All these investigations provide a basis for the bridge of linear control.
