| 摘 要： | 桥梁施工控制就是在结构分析基础上通过对施工过程中的应力及线形进行控制,对施工中出现的偏差进行分析识别,发现问题并及时进行纠正,同时对结构的后续阶段进行正确预测,最终目标使成桥状态达到设计要求。以松花江大桥为工程背景,详细的论述了本桥的线形控制理论及方法。利用M IDAS软件建立有限元模型,计算出预抛高值。针对松花江大桥现场施工监控的结果,详细比较了梁体阶段挠度、累计挠度、各阶段测点的计算值和实测值的关系;最终监控结果表明,本桥达到了线形平顺、受力合理的预期目的。

| Abstract: | Construction Monitoring of the bridge is based on analysis of the construction process of stress and linear control,with the error analyzed to identify the problem and correct it in time and at the same time making correct predictions for the subsequent stages.The ultimate goal of the finished bridge state is to meet the design requirements.In this article,based on the construction of Songhuajiang Bridge,the finite element model of the bridge is established by the MIDAS software to analyze the bridge constr... |
