带腹拱圈的拱桥受力分析及加固方法

该文通过对某拱桥的加固计算,分析了施工过程对既有桥和新桥受力计算的不同点,比较计算了两种方法下的结构内力。由分析可知,在对既有桥的计算时必须考虑成桥历史和加固施工过程。

Stress Analysis and Reinforcing Method of Arched Bridge with Web Arch Ring

Through the reinforcing calculation of an arched bridge, the article analyzes the different points of the stress calculations of the existing bridge and the new bridge in the course of construction, and compares and calculates the internal forces of the structures by two methods. Known from the analysis, it must be to consider the history of the built bridge and the course of the reinforcing construction during the calculation of the existing bridges.
