| 摘 要： | 结合千岛湖大桥施工及成桥的长期监测项目,通过实测数据分析,探讨了大跨径钢管混凝土拱结构的徐变效应问题。提出了实测弹性计算比的概念,根据该指标的分析,总结出四肢格构式钢管混凝土拱结构的长期受力状态和规律。这些结论和分析方法无论是对于钢管混凝土拱的徐变分析,还是大跨径钢管混凝土的拱桥设计,都提供了有益的参考。 |
| 关 键 词： | 钢管混凝土拱桥 徐变效应 长期监测 实测弹性计算比 |

| Abstract: | Combined with the construction and the long-term monitoring project of the Qiandao Lake Bridge,the creep effect of long span concrete-filled steel tubular(CFST) arch bridge structure is discussed through measured data,the concept of the ratio of measurement and elastic calculation is proposed and then the long-term stressing condition and rule of the four-limb trellis type CFST arch structure are summarized according to that target analysis.In a word,these conclusions and analysis method provide beneficial reference either to the creep analysis of CFST arch structures or to the design of long span CFST arch bridge structures. |
| Keywords: | CFST arch bridge creep effect long-term monitoring ratio of measurement and elastic calculation |
