摘　　要：以贵州省松桃至玉屏快速路项目中某高墩大跨连续刚构桥为案例,通过对结构特点进行分析,并使用有限元分析软件Midas Civil进行施工过程模拟计算,再与现场监测数据进行对比,以此确保整个施工阶段的应力正常。在桥梁竖向线形控制过程中,应用参数敏感性分析和灰色系统理论,将理论计算结果与施工过程中采集的数据进行对比,验证桥梁的施工安全性。In the case of a high-pier large-span continuous rigid frame bridge in the Songtao-Yuping Expressway project in Guizhou Province,the structural characteristics were analyzed and the finite element analysis software Midas Civil was used to simulate and calculate the construction process,and then compared with the field monitoring data to ensure normal stress throughout the construction phase.In the bridge vertical alignment control process,the application of parametric sensitivity analysis and gray system theory,the theoretical calculation results and the construction process of the data collected during the comparison to verify the bridge construction safety.
