预应力混凝土连续梁桥悬臂施工监控研究

Study on Cantilever Construction Monitoring of Prestressed Concrete Continuous Beam Bridge

根据未修正前的有限元模型,选取了几个对施工有较大影响的参数进行混凝土容重敏感性分析,以为修正模型提供参考,最后根据修正后的模型以验证所建立模型的可靠度。

Based on the uncorrected finite element model,this paper selects several parameters which have great influence on the construction to carry out sensitivity analysis,so as to provide reference for the modified model.Finally,according to the modified model to verify the reliability of the established model.
