有限元分析软件在连续梁线形监控中的应用

Application of finite element analysis softwarein linear monitoring with continuous beam

为保证大跨度连续梁桥的成桥质量,在桥梁施工过程中需要对影响桥梁内力及线形的因素进行监控量测。通过Midas Civil软件建立有限元梁单元模型并进行仿真模拟分析,在施工过程中通过对比实测数据及建模数据,对悬臂浇筑连续梁预拱度的取值进行研究总结,最终实现连续梁桥的精确合龙。本文研究成果可为类似工程提供借鉴。

In order to ensure the quality of the long-span continuous beam bridge,it is necessary to monitor and measure the factors that affect the internal force and alignment of the bridge during the construction process of the bridge.The beam unit model of finite element is established through Midas Civil software and the simulation analysis is performed.During the construction process,by comparing the measured data and modeling data,the value of the continuous beam pre-cam ber of the cantilevered pouring is researched and summarized,and the precise closure of continuous beam bridge is realized.The results can provide references for engineering and technical personnel participating in similar domestic projects.
