摘要
为给多跨连续拱桥加固改造施工监控工作提供指导,文章以藤县西江大桥为工程背景,借助有限元分析方法,详细阐述了多跨连续拱桥加固改造施工监控系统的建立和控制技术。实践表明:藤县西江大桥加固改造施工在严格监控下,结构安全,内力与线形均处于可控状态,所采用的监控技术措施具有较强实用性,可为类似工程提供借鉴。
In order to provide guidance for the reinforcement reconstruction monitoring work of multi- span continuous arch bridge,with Tengxian Xijiang Bridge as the engineering background,this article elaborated the establishment and control technology for the reinforcement construction monitoring system of multi-span continuous arch bridge by using the finite element analysis method.The practice showed that the reinforcement reconstruction of Xijiang Bridge in Tengxian County under the strict monitoring has the safe structure,and the internal force and linear are in a controlled state,thus the adopted monitoring technology measures have a strong practicality, which can provide reference for similar projects.
