摘要
对旧桥加固施工过程进行监测,是确保施工质量和安全、实现加固目标的重要措施。本文以某跨江大桥(钢桁架高架铁路组合桥)维修加固工程为例,建立MIDAS建立有限元分析模型,以应力和变形为监测参数,完成了加固工程的施工监测工作、数值模拟分析和现场试验,可以为其他类似工程提供有益的参考和借鉴。
Monitoring the reinforcement construction process of old bridges is an important measure to ensure construction quality and safety,as well as to achieve reinforcement goals.This article takes the maintenance and reinforcement project of the Zhicheng Yangtze River Bridge(steel truss elevated railway combination bridge)as an example,establishes a finite element analysis model using MIDAS,with stress and deformation as monitoring parameters.The paper successfully completes the construction monitoring,numerical simulation analysis,and on-site testing of the reinforcement project.This can provide useful reference and reference for other similar projects.
