摘　　要：以某铁路48m+80m+48m连续梁桥施工项目为例,针对工程建设期间的桥体线形、应力分布等内容进行监控和检测。论文通过过程监测得到施工各阶段主桥相应部位的设计应力和结构变形数值,通过对比上述数值,分析各施工阶段中主桥内力和主梁变化程度与相应的设计预测值间的偏差,从而对施工过程进行纠偏,帮助施工单位在保证安全的前提下高质量、高效地完成施工。Taking the construction project ofa 48 m+80 m+48 m continuous beam railway bridge as an example,the paper monitors and tests the linear shape and stress distribution of the bridge during the construction period,obtains the design stress and structural deformation values of the corresponding parts of the main bridge in each stage of construction Through process monitoring.By comparing the above values,the deviation between the change degree of the internal force and main beam ofthe main bridge in each stage of construction and the corresponding design prediction value is analyzed,so as to correct the deviation during the construction process,and help the construction unit to complete the construction with high quality and efficiency under the premise ofensuring safety.
