旧桥加宽局部温度影响研究

Research on partial temperature effect in old bridge broadening

以广州某桥加宽过程中温度荷载的局部影响为研究对象,分析了温度荷载单独作用下新加宽部分、旧桥部分及加宽后联合桥的应力和变形响应,得出温度荷载对加宽影响的结论,供类似工程问题参考。

Taking the partial effect of temperature load during a bridge＇ s broadening process in Guangzhou as the researching object, it analyzes the new broadening part, old bridge part as well as stress and deformed reaction of combined bridge after broadening, draws a conclusion that temperature load has impact on broadening, and can be reference for familiar project.
