摘要
在桥梁施工项目中,其质量的好坏直接决定着交通运输的安全性,与人们的日常生活以及工作等有着不可分割的联系。基于此,通过测量主梁线形结构参数,判断桥梁横截面应力横向分布,采用灰色预测理论,预测桥梁施工应力变化,对桥梁施工应力监测结果进行分析。再通过桥梁上层结构优化改造,加固原始桥梁基础结构、主桥箱梁外侧增设预应力混凝土结构等,对桥梁施工维修与加固技术进行研究,以期为桥梁建设的安全施工,以及桥梁养护与维修加工提供参考。
The quality directly determines the safety of transportation in the project of bridge construction,which has an inseparable connection with people's daily life and work.Based on this,the transverse distribution of stress on the bridge cross-section is judgedby measuring the linear structural parameters of the main girder,the grey prediction theory is used to predict the stress change of the bridge construction,and the stress monitoring results of the bridge construction are analyzed.And then the bridge construction maintenance and reinforcement technology are studiedthrough the optimization and reconstruction of the upper structure of the bridge,strengthening the original bridge foundation structure,and adding prestressed concrete structure outside the box girder of main bridge,so as to provide reference for the safe construction of bridge construction,as well as the bridge maintenance and repair processing.
