摘要
为使某钢-混叠合梁斜拉桥在成桥后其几何线形和应力与设计理想状态一致,分别对钢-混叠合梁斜拉桥计算、施工、测量中可能产生的误差进行分析。利用有限元软件建立全桥仿真模型,对工程实例进行结构参数敏感性分析,分析得出钢-混叠合梁斜拉桥成桥线形和应力的敏感参数。根据分析结果,提出相应的计算误差、施工误差及测量误差的控制方法。
In order to realize that the geometric shape and stress of a steel-concrete composite beam cable-stayed bridge are consistent with the design ideal state after completion of the bridge,the possible errors in the calculation,construction and measurement of the steel-concrete composite beam cable-stayed bridge are analyzed respectively.The full bridge simulation model is established by using finite element software,and the sensitivity analysis of structural parameters is carried out for an engineering example.The sensitive parameters of the finished alignment and stress of the cable-stayed bridge are obtained.According to the analysis results,the corresponding control methods of errors in calculation,construction and measurement are put forward.
