摘要
对五跨连续箱梁桥进行了荷载试验及数据分析,运用大型有限元程序Midas建立空间梁单元模型,对连续箱梁桥进行仿真分析,并对6种试验工况下桥梁变形和断面应力的实测值与理论值进行了比较,研究结果表明:桥梁变形和断面应力的实测值与理论值吻合较好,桥梁的结构强度和刚度达到了设计要求。
The paper carries out load test and data analysis of five-span PC continuous box girder bridge,establishes spatial beam model by applying large-scale finite element program Midas,carries out simulation analysis for continuous box girder bridge,and compares actual measurement value to theoretical value of bridge deformation and section stress under 6 kinds of experimental working conditions. Results show that： actual measurement value of bridge deformation and section stress is in accordance with its theoretical value,furthermore,both the bridge structure strength and rigidity meet design demands.
