摘　　要：以某大跨度连续箱梁桥为例,通过有限元软件桥梁博士进行建模分析,采用前进分析法计算得到桥梁各荷载下的变形值、弯矩、轴力、剪力等等,在施工过程中将理论计算值和实测结果进行比较,并及时反馈与调整,由此保证了该桥成桥线形满足规范及设计要求。This paper takes a long-span continuous box girder bridge as an example,carries on the modeling analysis through the finite element software Dr.Bridge,calculates the deformation value,bending moment,axial force,shear force and so on under each load of the bridge by the forward analysis method,compares the theoretical calculation value with the actual measurement result in the construction process,and timely feedback and adjustment,thus guarantees that the alignment of the bridge meets the specification and design seek.
