| 標(biāo)題 |
| 無橫撐鋼管混凝土拱橋靜動載試驗(yàn)研究(49 卷) |
| 英文標(biāo)題 |
| Study of concrete-filled steel tubular arch bridge without lateral bracing by static and dynamic test |
| 摘要 |
| 對某無橫撐鋼管混凝土拱橋?qū)嵤╈o力荷載試驗(yàn)和動力荷載試驗(yàn)，測試并分析靜載工況下的拱肋和系梁撓度、吊桿拉力、拱肋與系梁的截面應(yīng)力。試驗(yàn)結(jié)果表明，該橋受力合理，具有良好的剛度與強(qiáng)度。在動載試驗(yàn)中，測試其自振特性，進(jìn)行了跳車試驗(yàn)，并分析了在行車下的沖擊作用。 |
